Plants need to spread their seeds away from themselves to avoid overcrowding.

Seeds disperse by wind, water, catching a ride on animals, or moving in animal poop.

ExplainSome algae can grow from seeds, called spores, but most reproduce from fragments. Fragments are pieces that break away from an alga and can start an entire new alga.

What is one way algae reproduce?Fragmentation! Uncle says fragmentation means breaking into pieces. Hurricanes, tsunamis, rough currents, waves, and consumers can break algae in many pieces. Broken fragments (pieces) grow into new algae.

How does algae grow from a fragment?Breaks off from the parent algae and grows into a new algae! The process resembles an entire sea star growing from just one arm.

17

what’s in a word?

Phykos means seaweed in Greek. Phycologists study algae.

Did you know?

Algae can also reproduce by spores. Spores can travel through the water or air!

interesting fact

Very few animals begin their life cycle by fragmentation. Almost all animals require a mama and a papa.

Make a prediction.•

Test with an experiment. •Create a control: Place some algae in a jar with seawater. Leave in sun. Create a variable: Place some algae on a plate. Leave in sun. Record changes for a week.

Analyze data.•

Communicate results. •

How it worksDeath! The life cycle of all living things always ends with death. Algae die if eaten, dried, or smothered. Tutu says the algae on the plate died after all its water evaporated (dried). The algae in the jar may have died from too little carbon dioxide (smothered).

did you know?

Although both photosynthesize, scientists do not group algae with plants. Why? Algae do not have roots, stems, and leaves.

On a Related Note

Scientists organize algae by color (red, green, or brown) texture (fleshy,hard),orsize(micro/macro).

Interesting Fact

The lifespan of algae differ for each species. Some live for only a few days. Others live one or two years.

What’s in a Word?

Planula comes from the Latin word planum, meaning “somethingflat.”Thatreallydescribes the shape of coral larvae before it becomes a polyp.

Corals, of course

22



ExplainCorals start their life cycle inside an egg that hatches into a planula (larva). The planula lives as plankton until it is ready to transform and become a polyp (adult). Lots of adults live in polyp “apartment buildings” to make a reef.

Whatarethemiddletwostagesofacoral’slifecycle?Planula and colony! Polyps metamorphose from planula and cement themselves to pink-colored coralline algae. Then, they bud (clone themselves) into many to form a colony.

How do polyps create colonies?Budding! Some polyps do not go through an egg-planula-polyp-dead life cycle. Instead, they go through a bud-polyp-dead one. Uncle says polyps divide from an existing polyp in a process called budding. This expands the size of a coral colony using existing polyps that stay connected.

23

Scientists Say...

...fission when one coral colony splits into two colonies.

Did You Know?

A single polyp can leave a colony and move to a new place to start a new colony. That is known as “polyp bailout.”

ExplainMonk seals change from an egg inside their mother and, when born, become a pup (baby).

Whatisamonkseal’slifecycle?Egg - pup - adult - dead! Aunty says because monk seals are mammals, we do not see their eggs - but they have them! We notice the next stage, called a pup. Pups look like miniature adults, but have fur with a different color and texture.

Did you Know?

Monk seal mothers do not eat forthefivetosixweekswhilethey nurse their pups. They live off of energy stored in their fat (blubber).

On a Related Note

Think About It

How do monk seals with all of their blubber remain cool in the warm climate of Hawaii? Scientists do not know the answer!

When adult monk seals molt, which they do every year, they shed their skin and fur.

ExplainThe sea turtle life cycle goes egg - juvenile - adult - dead. After the eggs hatch, hatchlings head out to sea. Juveniles stay there for at least one year. As adults, they move into nearshore waters.

How do turtles begin their life cycle? Inside eggs! A mother digs a hole in the sand and buries her eggs for protection. She then returns to the ocean. Aunty says, after a couple of months, hatchlings emerge! Like all other reptiles, baby turtles look very much like adults, just smaller!

How do juvenile green sea turtles differ from adult green sea turtles?Diet and size! Juvenile turtles eat sea jellies, crabs, and shrimp. Uncle says when they become adults, they stop eating meat and only eat vegetables like seagrass and lots of algae!

Baby honu only dig out when the sand feels cool, so they hatch at night, when fewer predators hunt.

ExplainFor most ocean consumers, the life cycle starts with eggs, then larvae, juveniles, and lastly, adults. Eggs are special cells found in female animals. Nearly all animals produce eggs. Some animals have eggs only on the inside of their body. Some animals lay eggs outside their body.

How do octopuses begin their life cycle?

Eggs! A female octopus searches for a safe den to hide her eggs. She strings her eggs along the side of the den and fans water over them so they receive oxygen. She guards them until they hatch.

ExplainThe third life cycle stage for most marine consumers is juvenile. As juveniles, many marine animals eat zooplankton.

What are juveniles?Young adults! Juvenile is the third life stage of some marine animals. When some animals metamorphosize from a larvae to a juvenile, they start to look like smaller versions of their adult form with small variations, such as different colors or markings.

ExplainAll living things have a life cycle that ends in death.

Whatisamarineconsumer’slifecycle?Egg-larva-juvenile-adult-dead! Uncle says that simply put, the life cycle for marine consumers describes the stages through which they live and ends when they stop living.

What happens after living things die in the ocean? Eaten by detritivores! Detritivores eat dead consumers and producers. Aunty says detritivores, like crabs and lobsters, serve as the clean up crewforlivingthings’lifecycle.Whatwouldouroceanlooklikeifwehad no detritivores?

Think about it...What are the four main life cycle stages for most marine consumers?

ElaborateComplete the Life Cycle Sudoku Puzzle individually.

Cut out life cycle stages • (U5.L5.A9-page 74).Substitute the numbers for different parts of the life cycle:1=Egg2=Larva3=Juvenile4=Adult (and dead).

Paste different stages on their corresponding numbers.•Circle row that has the life cycle in the correct order from being born to dying.

How it workEgg-larva-juvenile-adult (and dead)! Most tropical marine animals, like coral, begin their lifecycleasanegg.Fromtheegg,theybecomelarvaeandfloatintheoceancurrents.After a month or two, they metamorphosize into their juvenile form. Uncle says they eventually transform into their adult form. The adults lay their eggs and eventually die.

EvaluateWhat is the fourth life cycle stage (and the end of the life cycle) for marine consumers?

Answer by creating a pata scroll individually.

Choose a marine producer or consumer you like.•Look at books to learn more about them.

Illustrate a story about its life cycle on a scroll.•Draw one picture per stage per paper. Leave white space on top of firstpageandbottomoflastpage.Yourcompletedpapersshouldbevertical (portrait) and not horizontal (landscape).

Outlineyourfinalversioninblackpen.•Color drawings with bright markers.

Tape all papers together.•You should form a single, long, vertical scroll for the entire class.

Staple each end to empty paper towel tube. •Tape along edges.

Roll entire scroll.•Take turns telling story to classmates as two assistants unroll scroll.

How are producers’ and consumers’ life cycles similar? How are they different?

...life expectancy for the average amount of years a certain animal usually lives.

Cultural Note

Pata scrolls are long vertical scrolls from Bengal. Storytellers slowly unwind their scroll as they sing and dance.

Interesting Fact

Pata scrolls are made on cloth treated with cow dung! They are brightly colored using vegetable dyes.
