in turn determine both the distribution of organisms and their abundance. Ecologists study how interactions between organisms and the environment affect phenomena such as the number of species living in a particular area‚ cycling of nutrients in a habitat‚ and the growth of populations. 2. Describe the relationship between ecology and evolutionary biology. Darwin’s extensive observations (ecological studies) of the distribution of organisms and their adaptations to specific environments led him

Explanation for another mineral resource In the extraction of petroleum a mining company would want to consider possible consequences which include: erosion and sedimentation‚ contamination of soil and habitat modification. Erosion and sedimentation present another environmental issue for mine sites. When material is disturbed in significant quantities‚ as it is in the mining process‚ large quantities of sediment are transported by water erosion. The sediment
