starts with sunlight and photosynthesis if you are talking about plants
The flow of energy moves through living organisms via the food chain. A food chain is a diagram which shows how every living thing gets energy to live. Plants use the sun, nutrients in the soil and water to generate energy. Herbivores eat the plants to generate energy to survive. Carnivores eat the herbivores to generate energy.
<span>Matter moves through the biosphere by being cycled through various organic and inorganic stages. They are neither created nor destroyed. The biosphere is known as a closed system so no elements can escape. They are continually being recycled. </span>
The example of a nonpoint source of freshwater is the first option: <span>pesticide runoff from farm fields. This is one of the most common nonpoint source of poullution</span>
Water is photolysed to produce electrons, H+ ions and O2.
The equations is 2H2O ->4H+ + 4e- + O2
Genes B and C with 10% recombination frequency are closest to each other. Because recombination happens at random, the distance between genes that are farther from each other creates higher recombination frequency. A low recombination frequency of 10% means the genes are closest to each other. The short distance between the two genes allow fewer recombination to happen, thus the frequency is low.
