What is natural selection?

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring. It is a key mechanism of evolution.

Front

Define adaptation in the context of living organisms.

Back

Adaptation refers to the process by which a species becomes better suited to its environment through changes in its physical or behavioral traits.

Front

What is the significance of body size in animal populations?

Back

Body size can affect an animal's survival and reproduction, influencing factors such as heat retention, food requirements, and predation risk.

Front

Explain the impact of environmental changes on species survival.

Back

Environmental changes can alter the availability of resources, leading to shifts in population dynamics, survival rates, and reproductive success.

Front

What is the role of food availability in animal populations?

Back

Food availability directly affects the health, reproduction, and survival of animal populations, influencing their growth and distribution.

Front

How does climate change affect animal behavior?

Back

Climate change can lead to shifts in migration patterns, breeding seasons, and feeding habits as animals adapt to new environmental conditions.

Front

What is the relationship between beak size and food sources in birds?

Back

Beak size in birds is often adapted to the type of food they consume; larger beaks may be advantageous for accessing larger seeds or prey.

Front

Define the term 'population density.'

Back

Population density refers to the number of individuals of a species per unit area or volume, influencing competition and resource availability.

Front

What is the effect of pollutants like DDT on wildlife populations?

Back

Pollutants like DDT can cause reproductive failures and population declines by affecting the health and viability of eggs and offspring.

Front

Explain the concept of ecological niche.

Back

An ecological niche is the role and position a species has in its environment, including its habitat, resource use, and interactions with other species.
