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

Ideally, an inventory of an ecosystem should be taken:

savanna

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?

the ecosystem of multiple organisms, regardless of a real extent

Concerning the balance of pollutants in the biosphere:

the long term balance of the biosphere under current conditions is uncertain

Biomes are usually named from:

the variety of flora
