Ecology is the study of __ among organisms with each other and their surrounding environments.

interactions

The two types of interactions in ecology are __ interactions and abiotic interactions.

biotic

The simplest unit of life is a __.

cell

An __ is a group of organisms of the same species occupying the same environment.

population

A __ is defined as the worldwide ecosystem, including the air, bodies of water, land, and soil.

biosphere

Organismal ecology includes the study of an individual organism's behavior, physiology, and __ in response to interactions with their abiotic environment.

morphology

The factors affecting population composition, size, and density are studied in __ ecology.

population

The interactions between populations of different species in a given area are studied in __ ecology.

community

Ecosystem ecology focuses on the responses and changes in the community due to interactions between and factors.

biotic, abiotic

Temperature, wind, and water are considered __ factors that limit the distribution of organisms.

abiotic

The __ is the most important factor in the distribution of organisms due to its effect on biological processes.

temperature

High salinity affects plant growth in terrestrial habitats and osmosis in __ environments.

marine and freshwater

Biomes can overlap and may __ into each other without sharp boundaries.

grade

The two major types of biomes are __ biomes and aquatic biomes.

terrestrial

Coral reefs are typically found in __, warm, and shallow waters.

tropical

Freshwater biomes are closely linked to the __ biomes that surround them or through which they flow.

terrestrial

Biogeography is influenced by __, as it plays an important role in how species are distributed across geographical areas.
