PENN FOSTER LESSON 5 BIOLOGY PROCTOR
REVIEW ( PLANT STRUCTURE AND FUNCTION)
What is biodiversity? Whats the difference in Direct VS Indirect values
- answer-variety of life in the world;
Direct values: medicines, foods, and other products that benefit humans
Indirect values: cannot always be measured economically
Patters of population growth
- answer-disruptive, stable, and linear
Compare opportunistic and equilibrium species
- answer-
types of succession
- answer-Primary: starts where soil has not yet formed
Secondary: starts where soil is already present (in a clutivated field that is no
longer farmed)
Compare autotrophs and heterotrophs
- answer-Autotrophs-make own food through photosynthesis
heterotrophs-consume; eat plants, animals, or decompose organic matter.
Transfer rate and eutrophication
- answer-Transfer rate is the amount of a nutrient that moves from one component
of the environment to another within a specified time
Eutrophication is the over-enrichment of a body of water, which caused a rapid
algal population growth called algal bloom
What is climate change and the greenhouse effect?
- answer-Climate change is drastic changes in climate; greenhouse effect is the
allowance of the sun's rays to pass through the atmosphere and reradiate heat back
to earth
What is the biosphere?
- answer-the part of Earth where life exists
