Ecology and Biodiversity Questions
A
Correct answer
Explanation
An ecosystem is defined by the interaction between living (biotic) organisms and their non-living (abiotic) environment.
A
Correct answer

-
A resource that is found in the hydroshere such as sea life.
-
A resource that is non-living, such as sunlight.
-
A resource that can't be used.

-
Abiotic Factor
-
Biodiversity
-
Adversary
A
Correct answer
Explanation
Biotic factors are the living components of an ecosystem, such as plants, animals, and bacteria. Abiotic factors are the non-living components, such as water, soil, and temperature.
-

-
Isolation
-
Fossil Fuels
-

-
plants & animals
-
humans & air molecules
-
carbon dioxide & oxygen particles
-
biotic & abiotic components
D
Correct answer
Explanation
A successful or functional environment requires both living (biotic) and non-living (abiotic) components to sustain life and nutrient cycles.
-
