Producers are very important to ecosystem reason being without the producers we would not be able to survive. Producers make their own food by use of sun which turns simple raw materials into food. Herbivores are consumers who eat only green plants. Omnivores eat animals and plants. Scavengers only eat dead organisms. Scavengers help the environment in that they eat dead organisms and decomposes the broken organic material down to the raw material.
A food chain is a linear sequence of transfer of food and energy when one organism is consumed by the other organism. Producers are the organisms which produce their own food by the process of photosynthesis. These includes plants and other autotrophs like some bacteria, and some protists. These organisms are consumed by the herbivores, and omnivores like humans. Producers support the wide range of diversity of other organisms. Herbivores are the organisms which are dependent upon plants and their products for their food needs like goat, sheep and deer. Carnivores are the organisms which feed upon herbivores. For example, lion, tiger. Omnivores are the organisms which can feed upon both plants and animals. The carnivores and omnivores maintain the balance of population of plants and animals in nature. Scavengers are the organisms which feed upon dead and remaining parts of the organisms. These organisms keep the environment clean by degrading the dead remains which facilitates the decomposition process by the soil microbes. For example eagle.
Explanation: facilitated diffusion us the carrier-mediated Transport of large molecules across the cell membrane using Transport proteins found in the cell membrane.such molecules include glucose,amino acids and ions.the passage across the membrane is from higher concentration to lower concentration
