Bullfrog

Objective: Learn How Habitat and Niche DifferKey Words: Niche, Habitat, Bullfrog

A mature bullfrog catches insects, worms, spiders, small fish, or even mice. Predators such as herons, raccoons, and snakes prey on bullfrogs. Bullfrogs spend their lives in or near the water of ponds, lakes, and slow-moving streams. A bullfrog’s body temperature varies with that of the surrounding water and air. As winter approaches, bullfrogs burrow into the mud of pond or stream bottoms to hibernate. Female bullfrogs lay their eggs in water during the warmer months of the year. The young frogs, called tadpoles live in the water until their legs and lungs develop.

An organism’s niche includes

• Its place in the food web

• The type of food the organism eats

• How it obtains this food

• Which other species use this organism as food

• The range of temperatures that the organism needs to survive

• When and how it reproduces

The area where an organism lives.

The role of an organism in the ecosystem.


• Define what a habitat is.

The organism’s habitat is like

• Define what a niche is.

Basketball positions in the offensive zone

One guard, two forwards, and two centers or two guards, two forwards, and one center were used.

1. Point guard: organizes the team's offense by controlling the ball.

2. Shooting guard: creates a high volume of shots on offense.

3. Small forward: responsible for scoring points via dribble penetration.

4. Power forward: plays offensively often with their back to the basket; on defense, plays under the basket.

5. Center: uses height and size to score (on offense), to protect the basket closely (on defense), or to rebound.

The Competitive Exclusion Principle


The competitive exclusion principle: •No two species can occupy the same niche in the same habitat at the same time.

Three Species of Warblers and Their Niches

1. Can two species share the same habitat?

2. Can two species share the same niche in the same habitat?

3. Can two species share the same niche in different habitats?





•No two species can occupy the same niche in the same habitat at the same time.

True or False?

•Two species can occupy the same niche in the same habitat at the same time.

•Two species can occupy the different niche in the same habitat at the same time.

•Two species can occupy the same niche in the different habitat at the same time.

•Two species can occupy the different niche in the different habitat at the same time.

List 2 things you learned about

•What a habitat is. Give one example.

•What a niche is. Give one example.

1. In a stable, long-existing community, the establishment of a single species per niche is most directly the result of

A) competition B) overproductionC) parasitism D) interbreeding

2. The ecological niches of three bird species are shown in the diagram below. What is the advantage of each bird species having a different niche?

A) There is less competition for food.B) Predators are less likely to feed on birds in a variety of locations.C) As the birds feed higher in the tree, available energy increases.D) More abiotic resources are available for each bird. 3. Although three different butterfly species all inhabit the same flower garden in an area, competition between

the butterflies rarely occurs. The most likely explanation for this lack of competition is that these butterflies

A) have a limited supply of food B) are able to interbreedC) occupy different niches D) share food with each other

4. In a forest community, a shelf fungus and a slug live on the side of a decaying tree trunk. The fungus digests and absorbs materials from the tree, while the slug eats algae growing on the outside of the trunk. These organisms do not compete with one another because they occupy

A) the same habitat, but different nichesB) different habitats and different nichesC) the same niche, but different habitatsD) the same niche and the same habitat

5. Areas with many different niches will most likely haveA) little diversity among the organismsB) no organisms that will become extinctC) great diversity among the organismsD) large numbers of organisms that will become extinct

An owl cannot entirely digest the animals upon which it preys. Therefore, each day it expels from its mouth a pellet composed of materials such as fur, bones, and cartilage. By examining owl pellets, ecologists are able to determine the
