What does a food chain represent?

A single path of energy transfer within a habitat.

How all living organisms within a habitat are connected.

All of the things that a particular animal eats.

How plants create their own food.

What is a trophic level?

Each level represented within a food chain or web.

Levels of ecosystems that the world is divided into.

Different levels of nutrients present within an organism.

The levels of sunlight an autotroph needs to survive.

An energy pyramid represents what?

The amount of energy available to the next 'feeder' in a food web.

How much sunlight is available for the ecosystem to use.

How much energy a particular organism needs.

How much energy is needed to build a pyramid.

Why is there a limited amount of energy that can be passed on to the next feeding level?

Organisms use some of the energy they get from eating.

There is never enough sunlight available.

Some ecosystems have limited resources.

All the energy is available to be passed on.

Why might an organism have more than one arrow coming from them in a food web?

More than one organism may eat them.

They may eat more than one other organism.

This organism gets its energy from multiple sources.

They have no resources available to them.

What may happen if the snowshoe hare was removed from the food web pictured?

The shrew population would decrease due to being only hawk food source.

The insects in the habitat would increase.

The willow tree population would decrease.

Foxes would dies due to no food source.

The diagram represents a model of a food pyramid. Which statement best describes what happens in this food pyramid?

Energy is lost to the environment at each level, so less mass can be supported at each higher level.

More organisms die at higher levels than at lower levels, resulting in less mass at higher levels.

When organisms die at higher levels, their remains sink to lower levels, increasing the mass of lower levels.

Organisms decay at each level, and thus less mass can be supported at higher levels

Which sequence shows the transfer of energy within an ecosystem?

producer ----> herbivore ------> carnivore -------> decomposer

carnivore -----> herbivore------> decomposer-------> omnivore

omnivore ------> carnivore -------> herbivore -----> primary consumer

producer ------> decomposer ----->herbivore -----> omnivore

What is an autotroph?

an organism that can make their own food.
