TYPES OF ECOSYSTEMS4. Describe each type of ecosystem and give examples of each.
Type of Ecosystem: _1)__ Terrestrial Ecosystem ___ Type of Ecosystem: _2)__ Aquatic Ecosystem ____
Definition:Terrestrial ecosystems are based on the land.
Examples: forest, grasslands, deserts
Definition:Aquatic ecosystems are based in the water.Marine ecosystems contain salt water. e.g. sea, oceanFresh water ecosystems contain fresh water. e.g. river, stream, lake, pond
Examples: sea, ocean, river, stream, lake, pond
Examples: Examples:
ANSWER KEY
Biology is the study of life.
The study of organisms within their environment. OR. The study of ecosystems.
A system where the biotic components interact with each other and with the abiotic components in order to sustain life.
animals, plants, fungi, decomposers
sunlight, water, wind, soil conditions, temperature
living nonliving

Type of Ecosystem: _3)__ Artificial Ecosystem _____ Type of Ecosystem: _4)____ Natural Ecosystem __
Definition:Artificial ecosystems are designed and managed by humans.
They have lower biodiversity.
Examples: parks, farms, schoolyard, Marine Land, zoo, backyard, aquarium
Definition:Natural ecosystems are NOT designed and managed by humans.
They have higher biodiversity.
Examples: field, meadow, stream, primary growth forest
BIODIVERSITY5. What is biodiversity?
6. How is biodiversity different in the two food webs below?
7. How does low or high biodiversity affect an ecosystem?
8.
It is a measure of the number of different types of organisms in an ecosystem.
Low biodiversity makes an ecosystem weaker.High biodiversity makes an ecosystem stronger.
Extinction of any one species would have a much greater impact in this food web because of its lower biodiversity.
Extinction of any one species would have much less impact in this food web because of its higher biodiversity.

b) How many hotspots have so far been identified in the world?

14. What is the ecological niche of the following organisms
a) deer b) bee
15. How do the ecological niches of the owl and the hawk overlap?
16. How do the ecological niches of the owl and the hawk differ?
17. Do any two species ever have exactly the same ecological niche? Why or why not?
The natural environment in which a species lives and which it depends on to meet all of its needs.
Habitat destruction is the #1 reason why most species become endangered or extinct in terrestrial ecosystems.
To build cities, and for agricultural land for growing crops and pasture land for farm animals.
25 hotspots identified so far.
It must have at least 1500 species of native vascular plants and lost 70% of its primary vegetation.
Geographic regions with significant biodiversity and which are under threat by humans.
Desertification, soil erosion, sedimentation of waterways.
It is the role an organism plays in its ecosystem.
The deer grazes on plants, and is food for various predators.
The bee pollinates many flowers and provides food for various predators.
They are both predators of rodents, and help keep their populations in check.
They are active at different parts of the day, and they hunt and nest in different areas.
Two niches are never exactly the same. This decreases competition amongst species and makes room for many more species in an ecosystem.

They need to be similar in appearance.
An individual organism of a species.
A group of similar ecosystems.
A community (biotic) and its abiotic environment.
A group of individuals of the same species in an area.
The sum of all of Earth’s ecosystems.
All populations of all species in an area.
They need to breed in natural environments.They need to be able to create healthy AND fertile offspring.
A hybrid is the offspring of two closely related but different species or the offspring of two members of the same species but of different breeds/strains/varieties.
The ability for populations of living things to continue to interact and reproduce indefinitely using the resources around them.
Acting to take personal responsibility for the care and management of the Earth.
