Biology Test - Ecology, Pollution, and Energy
The complex process of photosynthesis is responsible for:
- supplying energy to man - maintaining the food chain - converting energy to basic food
What are some examples of natural pollution?
- volcanoes - forest fires - floods
What impact does the various energy conversion processes have on ecology? 1. none of the above are related to ecosystems 2. energy conversion used by man usually produces pollution 3. natural energy conversion can help maintain/ restore balance 4. it is related to natural cycles which affect activities of ecosystems
2, 3, and 4
Why is satellite imagery useful to ecologists? 1. all natural factors can be identified 2. individual high resolution of ecosystems is possible 3. the fauna of an ecosystem can be counted 4. the predominant vegetation of an ecosystem can be monitored 5. small habitats can be observed 6. large-scale regional studies of biomes can be mapped 7. natural disasters can be surveyed 8. all vegetation types of ecosystems can be identified 9. outstanding environmental factors can be monitored
4, 6, 7, and 9
Pollution caused by pesticides and fertilizers is limited to areas close to the source (farms). True or False?
False
Natural catastrophes can upset the balance of an ecosystem. True or False?
True
Organisms and their nonliving environment are connected. True or False?
True
Recycling of garbage, solid wastes and certain crops for generating energy has been accomplished already. True or False?
True

What is meant by "solar radiation equilibrium" in the related ecology principle?
the complex atmospheric conditions combined with the net influx and radiation outflux produces a long term balance
What is true concerning an ecological community?
