Front

What is the role of the nervous system in animal behavior?

Back

The nervous system senses stimuli from the environment and sends signals to the muscular system to initiate movement or response.

Front

Define genetic drift.

Back

Genetic drift is a mechanism of evolution that refers to random changes in the frequency of alleles in a population over time, often having a more significant effect in small populations.

Front

What type of relationship is exemplified by a clownfish and a sea anemone?

Back

Mutualism, where both species benefit from the interaction.

Front

What is a predator-prey relationship?

Back

A feeding relationship where one organism (the predator) hunts and consumes another organism (the prey).

Front

What happens to prey population when predator population increases?

Back

The prey population will typically decrease due to increased predation.

Front

What is commensalism?

Back

A type of symbiotic relationship where one organism benefits while the other is neither helped nor harmed.

Front

Explain the concept of mutualism with an example.

Back

Mutualism is a symbiotic relationship where both organisms benefit, such as bees pollinating flowers while obtaining nectar.

Front

What is the significance of the muscular system in animal movement?

Back

The muscular system allows for movement by contracting and relaxing muscles in response to signals from the nervous system.

Front

Define the term 'ecosystem'.

Back

An ecosystem is a community of living organisms interacting with their physical environment.

Front

What is the difference between a food chain and a food web?

Back

A food chain is a linear sequence of organisms through which nutrients and energy pass, while a food web is a complex network of interconnected food chains.
