What is the correct order of ecological levels from less complex to complex?
species, population, community, ecosystem, biome and biosphere. Since you are asking specifically about the levels of organization in an ecosystem, we leave out the levels of biome and biosphere since they are both more complex than ecosystem. The most inclusive level in an ecosystem is the ecosystem itself.
Which is true about a population’s carrying capacity quizlet?
Carrying capacity is represented by K, used to study populations, and controlled by density-dependent factors (e.g. food). Furthermore, a population can temporarily exceed carrying capacity. However, resources will be limiting and the population size will return to below carrying capacity.
What is true of primary succession?
Primary succession is ecological succession that begins in essentially lifeless areas, such as regions in which there is no soil or where the soil is incapable of sustaining life (because of recent lava flows, newly formed sand dunes, or rocks left from a retreating glacier).
Which is true about a populations carrying capacity?
Carrying capacity can be defined as a species’ average population size in a particular habitat. The species population size is limited by environmental factors like adequate food, shelter, water, and mates. If these needs are not met, the population will decrease until the resource rebounds.
