Energy diagrams are use to depict the energy changes that occur during a chemical reaction. There are two types of reaction based on the energy change, these are exothermic and endothermic reactions. In endothermic reactions energy are gained while in exothermic reactions energy are lost to the environment. To identify an exothermic reaction on a potential energy diagram, one has to compare the potential energy of the reactants and the products. If the potential energy of the product is less than that of the reactants, the reaction is exothermic.
Answer:
when less water is flowing
The two biomes which have moderate precipitation levels are savanna and grassland.
Explanation:
An ecosystem includes both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which associates as a system. More importantly, the living things are very modified in the abiotic community because it cannot sustain by itself. Every animal, plant and human needs the primary physiological needs of water, food, and shelter provided by the abiotic system.
A biome is formed of several diverging ecosystems that relate to the community. Biomes can each be deserts, grassland, savanna, tropical rain forest, taiga, boreal and etc.
