Enviro. Science Final Exam (Light on Biodiversity)

Front

What is a community in ecological terms?

Back

A community is a collection of organisms that belong to different populations but all live in the same area and interact with one another.

Front

What is carrying capacity?

Back

Carrying capacity is the maximum size of a population that an environment can sustain indefinitely without degrading the environment.

Front

What is the primary function of the earth’s oceans in regulating climate?

Back

The oceans play a crucial role in global temperature regulation by absorbing and distributing solar energy.

Front

What occurs during subduction?

Back

Subduction occurs when a dense oceanic plate is pushed under a lighter continental plate, leading to geological activity such as earthquakes and volcanic eruptions.

Front

Define abiotic factors in an ecosystem.

Back

Abiotic factors are the non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems.

Front

What is the difference between a population and a community?

Back

A population consists of individuals of the same species living in a specific area, while a community includes multiple populations of different species interacting in that area.

Front

What is an ecosystem?

Back

An ecosystem is a biological community of interacting organisms and their physical environment.

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the diversity of species, genetic variation, and ecosystem diversity.

Front

What are niche and its significance in ecology?

Back

A niche is the role or function of an organism or species within an ecosystem, including its habitat, resource use, and interactions with other organisms.

Front

What is the role of producers in an ecosystem?

Back

Producers, such as plants and algae, convert solar energy into chemical energy through photosynthesis, forming the base of the food chain.
