Ecology-Food Webs and Succession

If a bird eats a mouse that eats grass, the bird is a(n)

producer.

second-level consumer.

first-level consumer.

decomposer.

The first organism in a food chain is typically a(n)

consumer.

herbivore.

carnivore.

producer.

In an energy pyramid, which level has the most available energy?

producer level

first-level consumer level

second-level consumer level

third-level consumer level

The many overlapping food chains in an ecosystem make up a(n)

food web.

niche.

energy pyramid.

feeding level.

The movement of energy in an ecosystem can be shown by an energy pyramid. An energy pyramid shows the amount of energy available at each level of a food chain. A food chain is made up of grain plants, mice, snakes, and hawks. Which of the following diagrams correctly represents the energy available at each level in this food chain? Use the image above

A

B

C

D

Looking at the model above, if the hawks are increased, what will happen to the grass? Please explain your reasoning.

Describe the role of decomposers in an ecosystem.

Which type of succession takes longer and why?

A) primary succession because it starts with soil

B) primary succession because it doesn’t have soil

C) secondary succession because it starts with soil

D) secondary succession because it doesn’t have soil

Which of the following represents a climax community in Michigan?

A) mosses, ferns and lichens

B) short grasses and shrubs

C) small, fast growing trees

D) tall, slow growing trees

What would most likely be the dominant community found in stage I?

A) tall grasses and slow growing trees

B) shrubs and fast growing trees

C) flowers and short grasses

D) mosses and lichens

What are the functions of the pioneer community?

In succession, plant populations precede, which means to come before, animal populations.
