Questions and Answers

What best describes mimicry in the context of animal behavior?

When one species resembles another that has recognizable traits. (correct)
A defense mechanism for blending into surroundings.
A strategy involving the consumption of different food types.
The ability to locate food sources effectively.

What is the primary function of camouflage in organisms?

To protect themselves by blending into their environment. (correct)
To attract mates through vibrant colors.
To establish dominance over other species.
To enhance their ability to hunt more effectively.

How do competing species typically adjust to coexist in the same environment?

By utilizing the same resources more efficiently.
By using different areas of the environment and consuming different foods. (correct)
By altering their fundamental niche to match their competitor.
By engaging in direct competition for resources.

The range of resources used by individuals or groups. (D) Signup and view all the answers

How does mimicry benefit the mimic species and what is a common example in nature?

Mimicry benefits the mimic species by helping it evade predators, often by resembling a more harmful or poisonous species; a common example is the viceroy butterfly mimicking the toxic monarch butterfly. Signup and view all the answers

In what ways does camouflage enhance an organism's chances of survival?

Camouflage enhances survival by allowing organisms to blend into their environment, making it harder for predators to detect them. Signup and view all the answers

What role does resource diversity play in the survival of a species within its ecosystem?

Resource diversity allows a species to occupy different niches, reducing competition and increasing their chances of survival in varied environments. Signup and view all the answers

Explain how the concept of niche differentiation helps species coexist in the same habitat.

Niche differentiation helps species coexist by allowing them to exploit different resources or habitats, which reduces direct competition for the same resources. Signup and view all the answers

What does it indicate about a stronger competitor if they have the same realized and fundamental niche?

If a stronger competitor has the same realized and fundamental niche, it indicates that the species is very efficient in resource use and dominates that niche, leaving little room for other species. Signup and view all the answers

Study Notes

Mimicry

One species of animal (the mimic) resembles another species that has easily recognizable characteristics.

Camouflage

Also called cryptic coloration
A defense mechanism that organisms use to disguise their appearance to blend in with their surroundings.

Resource Diversity

The diversity of resources used or environments tolerated by an individual, population, species, or clade.

Resource Partitioning

The process by which competing species use the environment differently in a way that helps them to coexist.
Competing species tend to compete less strongly
Competing species consume different foods
Using different areas of the environment reduces competition.
The stronger competitor will have the SAME realized and fundamental niche.

Mimicry

One species (the mimic) resembles another species.
The mimicked species has easily recognizable characteristics.

Camouflage

Also known as cryptic coloration.
A defense mechanism.
Organisms disguise their appearance.
Blend in with their surroundings.

Niche

Diversity of resources an individual, population, species, or clade uses.
Environments tolerated by an individual, population, species, or clade.

Resource Partitioning

Competing species use the environment in different ways.
Helps species coexist.
Species compete less strongly.
Consume different foods.
Use different areas of the environment.

Stronger Competitor

Has the same realized and fundamental niche.
