Ecosystem Components and Factors

This video tutorial covers essential vocabulary related to ecosystems, including terms like ecosystem, species, population, community, biotic factors, abiotic factors, and limiting factors. It explains how these concepts interact within a desert ecosystem, highlighting the roles of living and non-living components and their impact on organism populations.

What is an ecosystem?

• A group of the same species living together

• A non-living component of the environment

• A community of interacting organisms and their environment

• A single species in a specific area

Which of the following is an example of a species?

• Temperature

• Rock

• Coyote

• Sand

What does the term 'population' refer to in an ecosystem?

• The interaction between different species

• The number of organisms of the same species in an area

• The number of different species in an area

• The non-living components of an ecosystem

What is a community in an ecosystem?

• The temperature and climate of an area

• All the abiotic factors in an area

• A single species living in an area

• All the populations of organisms living together in an area

Which of the following is a biotic factor?

• Sunlight

• Water

• Grass

• Temperature

What is an abiotic factor?

• A non-living component that affects organisms

• A community of different species

• A group of the same species

• A living component that affects organisms

Which of the following is an example of an abiotic factor?

• Pronghorn

• Rock

• Javelina

• Coyote

What is a limiting factor in an ecosystem?

• A factor that limits the population size

• A factor that increases the population size

• A factor that only affects non-living components

• A factor that has no effect on the population

How do mountains act as a limiting factor?

• They provide water for organisms

• They increase the temperature

• They create a barrier that limits movement

• They provide food for organisms

Why is temperature considered a limiting factor in the desert?

• It provides shelter for organisms

• It is always cold in the desert

• It affects the availability of food

• It limits the number of organisms due to extreme heat
