Biological magnification is when an inorganic chemical is concentrated in a top carnivore as it feeds on lower levels of the food web that have this chemical in their tissues.
Food webs show the complex interaction between Food Chains. Food Chains shows a single line of producers and consumers.
Habitat is a place where an organism lives. IT can be described by the vegetation, type, or physical location. An example of a box turtles habitat would be pond and its associated shoreline.
Because they obtain a smaller amount of energy from each individual.
forest fires,storms, abandoned farmland
Provides a source of fresh air (oxygen), clean water, food, recreation, medicine
Primary succession occurs on surfaces that have not had living material previously (Rock). If soil is present, it is not likely a site of primary succession.
An orderly change in vegetation over time.
Pollution, Habitat Loss and Fragmentation, Invasive Species, Global Climate Change, Overexploitation of resources.
0.1 kilocalories
Omnivores eat plants and animals, carnivores eat animals only, herbivores eat plants only.
10 percent
Much of the energy is lost to heat.
Habitat fragmenation reduces the amount of habitat and resources available to a species. In addition, species lose genetic diversity as small populations are isolated in smaller habitats.
The base of the food web are the producers. Producers are organisms that make their own food. The levels above the producer are consumers. The consumers eat other organisms to obtain energy.
organism, population, community, ecosystem, biome, biosphere.
An autotroph makes its own food. Heterotrophs obtain their food from other sources.
A biome is defined by its vegetation and climate patterns. Soil is also important characteristic.
Secondary succession occurs where organisms have previously lived. Soil must be present for secondary succession to occur.
Biodiversity is the total variety of life in an area
To break down materials into smaller nutrients that can be absorbed by other organisms.
deciduous forest, cold winters
Flowing water biome.
