Describe the difference between a food chain and a food web.(1 point)
Responses
A food chain represents one possible pathway that energy and matter can take in an ecosystem. A food web contains multiple, interconnected food chains.

Why is the water cycle important for ecosystems?(1 point)
Responses
The water cycle permanently removes water from underground and from large bodies of water and transports it to terrestrial ecosystems.

The water cycle uses photosynthesis to make clouds. These clouds make surface water that animals drink to survive in their ecosystem.
