G8 BIO 6 Components of an Ecosystem

It consists of the biological community that occurs in some locale, and the physical and chemical factors that make up its non-living or abiotic environment.

• Ecosystem

• r-selection

• Ecological footprint

• Age structure

Which of the following are abiotic components of an ecosystem ?

• Deer, caterpillar, and grasshopper

• Flower, soil, and mountain

• Growth of grass

• Soil on the ground

Temperature is an example of_____.

• Biotic factor

• Abiotic factor

• Population density

• Population dispersion

What does a community consist of?

• Biotic and abiotic factors of an ecosystem

• All of the living organisms in an ecosystem

• All that affects the climate and weather

• Herbivores, carnivores, omnivores, and detritivores

In this ecological relationship, both organisms benefit from their interaction.

• Mutualism

• Commensalism

• Parasitism

• Predation

The struggle between organisms to survive as they attempt to use the same resource is called _____.

• predation

• competition

• mutualism

• commensalism

_____ reproduces repeatedly, has few offspring each time, cares for the young, and has high expectation for their survival.

• r-selected species

• K-selected species

This is the most common dispersion pattern for populations in which individuals "flock together".

• Clumped dispersion

• Random dispersion

• Uniform dispersion

The biotic or abiotic factors that control the size of a population keeping it at or below full potential is called _____.

• environmental resistance

• density-dependent factors

• carrying capacity

• biotic potential

It measures the area of biologically productive land and water that a population uses, with current technology, to generate resources it consumes and to absorb it wastes.

• Biotic potential

• Environmental resistance

• Carrying capacity

• Ecological footprint
