Investigating the Effects of An Abiotic Factor on the Frequency and Distribution of a Freshwater Invertebrate

Study the influence of abiotic factors on the frequency and distribution of freshwater invertebrates (i) Plan ------------ Introduction ============ Complex organisms Academic research must clarify the terms of the above heading for planning and development. In this survey, it is necessary to fully understand ecology in the study of relationships with living organisms, animals or insects, and biological environments.

Biogeography is the study of abiotic factors that influence the geographical distribution and distribution of organisms. Abiotic factors such as temperature and rainfall are mainly determined by latitude and altitude. As these abiotic factors change, the composition of plants and animal communities also changes. Ecologists studying biogeography will study the pattern of species distribution. There are no species anywhere; for example, Flytrap of Venus is unique to small areas of North Carolina and South Carolina. Eigen species are naturally occurring only in certain geographical areas and are usually of limited size. Other species are generalists: species living in different geographical areas, such as raccoons, are the most native of North America and Central America.

In some cases, biological factors may interfere with the function of abiotic factors. Excessive population of species affects abiotic factors and may adversely affect other species. Even the smallest organisms like phytoplankton can destroy ecosystems if overpopulation is allowed. This can be seen in "flowers of brown algae". There, too many algae accumulate on the water, prevent sunlight from reaching the lower area, effectively kill all life in the water. On land, when the canopy grows over a large area, a similar situation can be seen, effectively preventing the sun from reaching the underlying plants.

The flow is formed by the gravity that causes the flow of water on land. Many invertebrates live on the bottom of the river, making benthic communities. There are many factors that affect the distribution of invertebrates. These factors can be divided into two groups: abiotic and biological. v Average Matrix Type / Size - The size of the particles deposited on the bed bed depends on the flow rate / speed. That is, the lower the speed, the lower the kinetic energy of particle movement or transport.
