FREE Bachelor of Landscape Architecture Environmental Science Ecology Questions and Answers

Question 1

Using water temperature as an example

Accepted Answer

an abiotic factor.

Answer

Abiotic factors are the non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems. Water temperature is a physical characteristic of the environment, not a living component. Therefore, it is classified as an abiotic factor because it is a non-biological influence on an ecosystem.

Question 2

a group of creatures that come from many populations yet coexist in the same space and communicate with one another.

Accepted Answer

Community

Answer

A community in ecology refers to all the different populations of various species that live and interact in the same area. It encompasses the biotic (living) components of an ecosystem, excluding the abiotic (non-living) factors. The description precisely matches this definition, as it specifies multiple populations coexisting and communicating.

Question 3

the entirety of the environment's nonliving components as well as the group of species that make up a community.

Accepted Answer

Ecosystem

Answer

An ecosystem is defined as a biological community of interacting organisms (the biotic components) and their physical environment (the abiotic components). This includes both the living species and all the non-living factors like water, soil, and sunlight. The question's description perfectly aligns with the comprehensive definition of an ecosystem.

Question 4

Which of the following sums up a community the best?

Accepted Answer

sharks, groupers, anemones and shrimp on a coral reef

Answer

A community consists of different populations of various species living and interacting in the same area. Option D describes multiple distinct species (sharks, groupers, anemones, shrimp) coexisting and interacting within a specific habitat (a coral reef). The other options describe either a single population or a broad biome, not an interacting group of diverse species.

Question 5

Which thin layer supports life and has the highest ecological organization?

Accepted Answer

The biosphere

Answer

The biosphere represents the sum of all ecosystems on Earth, encompassing all life and the areas where life exists. It is the highest level of ecological organization, extending from the deepest parts of the ocean to the highest mountains where life can be found. This thin global layer is where all living organisms interact with the physical environment.
