Ecosystem

Question 6

Climax community

Answer 6

Stable, end stage of ecological succession in which the plants and animals of a community use resources efficiently and balance is maintained by disturbances such a fire, volcano, or glacier.
A final stable community, (after either primary (no soil) or secondary succession-soil present)

Question 14

Pioneer species

Answer 14

a group of hardy organisms, such as lichens, found in the primary stage of succession and that begin an area’s soil building process.

Question 15

Limiting Factors

Answer 15

Anything that restricts the size of the population, including living and nonliving features of an ecosystem, such as predators or drought.

Question 16

. Predator

Answer 16

Consumers that capture and eat other consumers.

Question 17

Prey

Answer 17

The organism that is captured by the predator.

Question 18

Energy Pyramid

Answer 18

A model that shows the amount of energy available at each feeding level in an ecosystem.

Question 19

Soil

Answer 19

mixture of mineral and rock particles and also the remains of dead organisms, air, and water that forms the topmost layer of the Earth’s crust and supports plant growth.

Question 20

Soil pH

Answer 20

The measure of the acidity or alkalinity of soil. Most plants grow between the 5.5-7 range of soil. If the soil is less than seven, then the soil is acidic. If the range is over 7-14, then the soil is base or alkaline.
