Which statement is true about Ecosystem A?

• It is a freshwater ecosystem surrounded by land

• It is a saltwater ecosystem that is divided by continents

• The ecosystem is shallower than lakes

• The temperature of the water stays the same from top to bottom

Why is there a large amount of organisms in the shallower parts of ecosystem A?

• Organisms have plenty of space to make a home

• Organisms are well-protected in that water zone

• Organisms prefer to live in places where a lot of humans visit

• Organisms have plenty of food as more sunlight is available to producers

What is a common feature between Ecosystem A and Ecosystem B?

• Both are freshwater ecosystems

• Both are saltwater ecosystems

• Both contain different plants and animals at different depths

• Both contain a deep bottom zone where sunlight does not reach

The striped bass is a type of fish that lives in Ecosystem B and that the heron eats as part of its diet.

If all other environmental conditions remain the same, which event would occur if the stiped bass population was to increase in Ecosystem B?

• The heron population would increase

• The heron population would decrease

• The bald eagle population would slowly decrease and then sharply increase

• The bald eagle population would remain constant

Sara goes on a trip with her family during the spring. They go for a walk and Sara makes observations. She notices many different types of large trees, grasses, and shrubs. She sees many small animals like squirrels, rabbits, foxes, and hears lots of birds. She also sees mushrooms on some fallen trees. Sara notices the temperature is warm but not too hot.

She creates the following model for how energy flows through the ecosystem.

GRASS -> RABBITS -> FOX -> HAWK

Sara claims that her family is visiting a forest ecosystem. Which evidence supports her claim?

• There are many types of grasses but very few trees and shrubs

• There are many tall trees and a variety of birds and animals

• The temperature in the spring is very hot

• The temperature in the spring is very cold

GRASS -> RABBITS -> FOX -> HAWK

What would happen if the number of rabbits increased? SELECT ALL THAT APPLY

• There would be more food for the foxes

• The hawk's food would decrease

• There would be no change in the food chain

• The amount of grass would decrease.

GRASS -> RABBITS -> FOX -> HAWK

Based on the food chain, how are the fox and the grass connected?

• The fox eats the rabbit for energy, and the rabbit depends on the grass for energy

• The fox prepares food for the grass using the sun, and the grass gives water to the fox

• The fox and the grass both use the sun to make their own food

• The fox and the grass both use the rabbit for energy
