This is all the living and non living things in an environment and the many ways they interact.
What is an ecosystem?
100
All living things in the ecosystems need these things in order to grow and reproduce.
What is water, nutrients, growing space and the right temperature?
100
This is the transfer of energy from one organism to another by eating and being eaten.
What is a food chain?

Describe how the wings of an eagle help the eagle survive.
The wings allow the eagle to fly. Flying helps it find prey, which the eagle needs to survive.

How does energy come to an ecosystem?
From sunlight.
200
In this ecosystem, it's very cold. The ground beneath the surface is cold all year. Trees cannot grow here, but some grass can.
What is the tundra?
200
Plants are called this because they make their own food.
What are producers?
200
This is a system of overlapping food chains in which the flow of energy branches out in many directions.
What is a food web?
200
What makes up an ecosystem?
Living and non living things and their interactions.
200
Which of these things might trees compete for an environment? Ecosystems Consumers Populations Resources
What is resources?
300
This ecosystem is known to be mild and rainy.
What is the rainforest?
300
These living things eat other living things
What are consumers?
300
What is the correct order of this food chain? Grass, owl, sun, mouse
What is sun, grass, mouse, owl?

In most food chains, 9/10 of the energy that an animal gets from its food is used by the animal. What fraction of the food energy is not used?
What is 1/10?
300
What ecosystem would an animal with webbed feet most likely live?
What is a wetland?
400
This ecosystem is very dry.
What is the desert?
400
These living thing only eat plants.
What are herbivores?
400
How is a food web different than a food chain?
A food chain is only one path of energy through an ecosystem. A food web is many overlapping paths of energy through and ecosystem.

How do the fins of a sunfish help it survive in a river?
The fins help the sunfish swim.

A group of organisms of the same kind living in a area is a what?
What is population?

What are wetlands?
500
These living things only eat meat.
What are carnivores?
500
What is one result of organisms competing for the same resources in an ecosystem?
It leads to their populations increasing no decreasing.
500
Can there be an ecosystem that only has carnivores? Why or why not?
No. An ecosystem needs a producer to absorb sunlight in order to make food.

In a simple food chain, a frog eats insects and a snake eats the frog. The primary role of the frog in the food chain is what?
