100

The total number of organisms in a specific area

Population density

100

Any factor that restricts the growth or abundance of a population in an ecosystem.

limiting factor
100

The maximum number of species that the environment can sustainably support.

carrying capacity

100

How is carbon removed from the atmosphere?

photosynthesis

100

What puts CO2, carbon dioxide, into the atmosphere?

Burning fossil fuels (respiration)

200

The type of distribution that is evenly spaced between individuals

uniform

200

The type of limiting factor that occurs due to living organisms.

biotic limiting factor
200
The type of growth seen when resources are limited in an ecosystem.
logistic growth
200

What 3 things do plants need to survive?

carbon dioxide, water and sunlight

200

Which of the following contain carbon?, NaCl (salt), C6H12O6, glucose (a form of sugar), or H2O (water)?

C6H12O6, glucose

300

The type of distribution that has organisms all together

clumped

300

The type of limiting factor that occurs do to abiotic issues within the ecosystem.

Abiotic limiting factor

300

The type of growth seen in organisms when resources are not limited.

exponential growth

300

What 2 things do plants make with carbon dioxide, sunlight and water?

Oxygen O2 sugar C6H12O6

300

What returns carbon dioxide to the ground?

dead or decaying organisms

400

The type of distribution that has organisms in different places all over.

random
400

Give 3 examples of a biotic limiting factor.

Competition, predation, disease

400

Contrast immigration vs emigration.

Immigration is movement INTO an area. Emigration is movement OUT of an area.

400

What are the reactants of photosynthesis?

carbon dioxide, water and sunlight

400

Which of the following DO NOT contain carbon?, NaCl (salt), C6H12O6, glucose (a form of sugar), or H2O (water)?

salt, NaCl & water H2O

500

What is the population density of 10 organisms living in 2 square meters?

5 organisms/m

500

Give 5 examples of abiotic limiting factors.

natural disasters, temperature, humidity, pH, space, sunlight, etc...

500

Why would bears of Alaska choose one location over another to live?

Any answer that states the idea that resources such as food, space, water, etc... are not as limited as in other areas.

500

What are the products of photosynthesis?

sugar and oxygen

500

What do plants do with the carbon dioxide that is removed from the air during photosynthesis?

It is made into glucose (sugar) by the plant so it can grow.
