This characteristic of life means that living things can create offspring in sexual and asexual ways

What is reproduction?

200

This process involves nitrification, ammonification, and denitrification.

What is the nitrogen cycle?

200

This is the name of an organism that can produce it's own energy in an ecosystem (also known as a producer)

What is an autotroph?

200

This type of growth is characteristic of a 'j-curve'

What is exponential growth?

200

The range of ________ means what conditions an organism can live in

What is tolerance?

200

Viruses need this to 'reproduce'

What are host cells?

300

This process involves weathering and erosion

What is the phosphorus cycle?

300

When niches overlap, it creates this biotic, density-dependent factor that limits a carrying capacity

What is competition?

300

This is the term for the maximum amount of organisms that can live in a given area of land

What is the carrying capacity?

300

Little precipitation

Varying, extreme temperatures

500

This is the name of the process for changing forms of nitrogen (example: changing gaseous nitrogen into solid, usable nitrogen)

What is fixing/fixation?

500

This term means that toxins accumulate in ecosystems in larger quantities as they move up food chains
