Quiz 1: Principles of Ecology
Examples of good management to maintain or restore the balance of nature are:
adjust living things to the environment, duplicate natural processes of the environment, and make decisions based on biology, ecology, and environmental decisions.
What part of an ecosystem could not surive without the other components?
carnivores
The complex process of photosynthesis is responsible for:
converting energy to basic food, supplying energy to man, and maintaining the food chain.
Which ecosystem is the most resistant to permanent change?
diverse organisms in a large region
A state of change in which the end result is equal or balanced
dynamic equilibrium
a condition or conditions of the nonliving surroundings, such as light, temperature, water, and so on
environmental factor
All forms of life on earth are linked together in relationships involving _____.
food
A series of food energy steps from plants to animals to other animals in a community of living things
food chain
the place where a community of plants and animals lives; the place where some organism is usually found
habitat
What are the environmental factors?
light, temperature, water, air, minerals, elevation, surface features, and growing seasons.
Which answer best indicates the dynamic balance of an ecosystem?
number and variety of organisms vs. changing environment
Putting together food molecules with chlorophyll and the light energy from the sun
photosynthesis
The tiny, free-floating plants in a lake or ocean; microscopic green algae
phytoplankton
The tiny, free-floating surface organisms of a lake, stream, or ocean
plankton
What are the main components of an ecosystem?
sun, soil, water, climate, green plants, herbivores, carnivores, and decomposers.
What is meant by "solar radiation equilibrium" in the related ecology principle?
the complex atmospheric conditions combined with the net influx and radiation outflux.
The tiny, free-floating animals in a lake, stream, or ocean; rotifers, brine shrimp, and water fleas
zooplankton
