Biological Diversity

Question 1

What is a variation in biological terms?

Answer 1

A difference in traits among individuals of the same species or between different species

Variations can affect survival and reproduction.

Question 2

Define adaptations.

Answer 2

Traits that enhance an organism’s ability to survive and reproduce in its environment

Adaptations can be structural, behavioral, or physiological.

Question 3

What are the types of variation?

Answer 3

• Interspecific variation
• Intraspecific variation

Interspecific variation occurs between different species, while intraspecific variation occurs within the same species.

Question 4

Complete the following fable comparing interspecific and intraspecific variations:

Interspecific variation involves _______ while intraspecific variation involves _______.

Answer 4

different species; the same species

This highlights how variations can occur at different levels of biological classification.

Question 5

What is biodiversity?

Answer 5

The variety of life in the world or in a particular habitat or ecosystem

Biodiversity includes the diversity of species, genetic variation, and ecosystem diversity.

Question 6

Explain why a coral reef ecosystem is considered to be more biodiverse than a desert ecosystem.

Answer 6

Coral reefs support a greater variety of species and complex interactions compared to deserts

Coral reefs provide numerous niches and habitats, leading to higher species richness.

Question 7

What is the role of natural selection in biological diversity?

Answer 7

It drives the evolution of species by favoring traits that enhance survival and reproduction

Natural selection leads to adaptations that contribute to biodiversity.

Question 8

Define population in the context of biological diversity.

Answer 8

A group of individuals of the same species living in a specific area

Populations can vary in size, density, and genetic diversity.

Question 9

What does community refer to in ecology?

Answer 9

A group of different species living together in a particular area

Communities interact with each other and their environment, contributing to ecosystem dynamics.
