Front

What happens to the energy that is not transferred in a food chain?

Back

It is lost as heat.

Front

How would you describe the rain forest biome based on its producers, consumers, and predators?

Back

It has high biodiversity.

Front

According to the 10 percent rule, if a trophic level has 1000 units of energy, how much energy would you find in the next trophic level?

Back

100 units.

Front

What is the correlation between the amount of available niches in an ecosystem and the amount of biodiversity it has?

Back

More niches, more biodiversity.

Front

Define a trophic level in an ecosystem.

Back

A trophic level is a position in a food chain or food web that is defined by how organisms obtain their energy.

Front

What is the primary source of energy for most ecosystems?

Back

The sun.

Front

Explain the concept of biodiversity.

Front

What is a food web, and how does it differ from a food chain?

Back
