What is Ecology?

Back

Ecology is the branch of biology that studies the interactions among organisms and between organisms and their environment.

Front

What is a Food Web?

Back

A food web is a complex network of feeding relationships among various organisms in an ecosystem, showing how energy and nutrients flow through the environment.

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, a cell will shrink or shrivel due to the loss of water.

Front

What are the products of light-dependent reactions in photosynthesis?

Back

The products of light-dependent reactions include ATP, NADPH, and Oxygen. Glucose is not produced in these reactions.

Front

What is predation?

Back

Predation is a biological interaction where one organism (the predator) hunts and consumes another organism (the prey).

Front

What is a Food Chain?

Back

A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organic material, recycling nutrients back into the ecosystem.

Front

What is mutualism?

Back

Mutualism is a symbiotic relationship where both organisms benefit from the interaction.

Front

What is commensalism?

Back

Commensalism is a symbiotic relationship where one organism benefits and the other is neither helped nor harmed.

Front

What is the difference between a hypertonic and hypotonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the cell, causing it to shrink, while a hypotonic solution has a lower concentration of solutes, causing the cell to swell.
