A complex model of feeding relationships, describing the connections among all food chains within an ecosystem.
a) Biomass pyramid
b) Food web
c) Ecological pyramid
d) Ecosystem

A general term used to describe one or more communities that are interacting with their environment as a defined unit. Ecosystems range from small units occurring in microhabitats, to larger units such as landscapes and seascapes, even the biosphere.
a) Food web
b) Biome
c) Habitat
d) Ecosystem

The study of the relationships between organisms and their environment.
a) Biology
b) Chemistry
c) Physics
d) Ecology

A model of the trophic structure of an ecosystem, organized with plant productivity on the bottom, that of herbivores above, and carnivores above the herbivores.
a) Ecological pyramid
b) Ecosystem
c) Biomass pyramid
d) Food web

The prevailing, long-term, meteorological conditions of a place or region, including temperature, precipitation, wind speed, and other factors.
a) Climate
b) Biome
c) Habitat
d) Ecosystem

Autotrophic productivity that utilizes energy released during the oxidation of certain inorganic chemicals (such as sulphides) to drive biosynthesis.
a) Photosynthesis
b) Bioaccumulation
c) Chemosynthesis
d) None of these

Microorganisms that harness some of the potential energy of certain inorganic chemicals (e.g., sulphides) to drive their fixation of energy through chemosynthesis.
a) Chemoautotroph
b) Autotroph
c) Heterotroph
d) None of these

A geographically extensive ecosystem, occurring throughout the world wherever environmental conditions are suitable.
a) Habitat
b) Biome
c) Biodiversity
d) Aquifer

The chemical potential energy of plant biomass, which can be combusted to provide thermal energy.
a) Biodiversity
b) Ecological pyramid
c) Habitat
d) Biomass energy

The richness of biological variation, including genetic variability as well as species and community richness.
a) Habitat
b) Biome
c) Biodiversity
d) Biomass pyramid

Groundwater resources in some defined area.
a) Aquifer
b) Aquaculture
c) Biome
d) Habitat

An organism that synthesizes its biochemical constituents using simple inorganic compounds and an external source of energy to drive the process.
a) Autotroph
b) Chemoautotroph
c) Heterotroph
d) None of these

The cultivation of fish and other aquatic species.
a) Habitat
b) Biome

d) Aquifer

Flowering plants that have their ovules enclosed within a specialized membrane and their seeds within a seedcoat.
a) Angiosperm
b) Gymnosperm
c) Producer
d) Consumer
