What is biodiversity?

• The study of rocks and minerals

• The variety of life on Earth, including organisms and ecosystems

• The number of people living in a certain area

• The process of photosynthesis

What does population growth refer to?

• Population growth refers to the decrease in the number of individuals in a population.
• Population growth is the migration of individuals from one area to another.
• Population growth indicates the aging of a population without any change in numbers.
• Population growth refers to the increase in the number of individuals in a population.

Population density is BEST describe by which statement?

• Population density is the number of individuals living per unit area.
• Population density is the measure of resources available in a habitat.
• Population density refers to the average age of individuals in a population.
• Population density is the total number of species in an ecosystem.

Which of the following is an example of density dependent limiting factor?

• Competition for resources
• Weather conditions
• Natural disasters
• Predation by animals

What is a limiting factor?

• A limiting factor is a condition that enhances the population size of an organism.
• A limiting factor is an unlimited resource that promotes growth.
• A limiting factor is a resource or condition that limits the growth or abundance of an organism or population.

• A limiting factor is a type of organism that thrives in any environment.

Which of the following can greatly affect the environment?

• Weather patterns
• Animal behavior
• Human activities
• Natural disasters

Why do you think some of the wildlife in most of the places in our country are endangered?

• Wildlife are endangered due to overpopulation of species.
• Endangered wildlife are primarily found in urban areas.
• Some wildlife in our country are endangered due to habitat loss, poaching, pollution, and climate change.
• Most wildlife are endangered because they are not popular with tourists.

When does population exhibit logistic growth?

• When environmental conditions are optimal for growth.
• When the population is in a state of decline.
• When resources are limited and a carrying capacity is reached.
• When resources are abundant and growth is unrestricted.

The following are human activities that have negatively impacted biodiversity EXCEPT

• Pollution
• Deforestation
• Overfishing
• Conservation efforts
