Exam 18: An Introduction to Ecology and the Biosphere

What level of ecology is concerned with the adaptations of individuals?

What level of ecology is concerned with groups of individuals of the same species?

Examine the figure below.Which part of Earth receives the greatest intensity of solar radiation?

Ecology is the study of ______.

In what part of the ocean are phytoplankton found?

Please read the following scenario to answer the following question(s). Salmon eggs hatch in freshwater streams and, during the first year of their life, the young salmon migrate up to 1,000 km to the ocean. They spend varying amounts of time in the ocean (ranging up to five years), where they feed and grow, rapidly acquiring more than 95% of their biomass during this period. During the summer of their maturing year, they begin the long journey back to their home streams where they spawn. Although it is still uncertain how salmon navigate back to their spawning grounds, current hypotheses suggest that they have a highly developed sense of smell. At the spawning grounds, females use their tails to form a hollow cavity where they lay up to 8,000 eggs. The male fertilizes the eggs, and both adults typically die soon thereafter. -At different times in their lives,salmon can be found in all of the following except ______.

Which of the following actions would increase your carbon footprint?

The greenhouse effect causes an increase in global temperatures.This increase is primarily due to ______.

Water-storing plants and deeply-rooted shrubs are plants that characterize ______.

The temperate zones ______.

With regard to the environment as a whole,when is the worst time to apply pesticide to your lawn?

Which of these biomes is maintained by fire?

What level of ecology is concerned with both the biotic and abiotic aspects of an environment?

Water moves from land to the atmosphere through _____.

Permafrost,or permanently frozen subsoil,characterizes _____.

______ are the dominant herbivores of savanna ecosystems.

Temperature increases due to global warming have been greatest _____.

If you study how two species of finches compete for food,you are trying to answer a question about _______.

What name is given to the region where sea meets land?
