What is a food chain?

Back

A food chain is a linear sequence that shows how energy and nutrients flow from one organism to another in an ecosystem, typically starting with a producer and ending with a top predator.

Front

What role do producers play in a food chain?

Back

Producers, such as plants, create their own food through photosynthesis and form the base of the food chain.

Front

How does a decrease in a predator population affect herbivore populations?

Back

A decrease in predator populations can lead to an increase in herbivore populations, as there are fewer predators to control their numbers.

Front

What is the relationship between herbivores and producers in a food chain?

Back

Herbivores are consumers that eat producers (plants) to obtain energy.

Front

What is the primary factor affecting salt levels in a salt marsh?

Back

The closeness of the marsh to the ocean primarily affects the amount of salt in a salt marsh.

Front

What happens to the population of producers if herbivores increase?

Back

If herbivore populations increase, the population of producers may decrease due to overgrazing.

Front

What classification do herbivores fall under in an ecosystem?

Back

Herbivores are classified as consumers because they consume plants for energy.

Front

What is the effect of an increase in carnivores on herbivore populations?

Back

An increase in carnivores typically leads to a decrease in herbivore populations due to increased predation.

Front

Can you give an example of a food chain?

Back

An example of a food chain is: grass -> grasshopper -> bird.

Front

What is the significance of energy transfer in a food chain?

Back

Energy transfer in a food chain is significant because it illustrates how energy moves through an ecosystem, from producers to various levels of consumers.
