Food Chains PowerPoint Presentation free download Biology Diagrams Producers are, in fact, plants. So, we can say that almost the food chain begins with a green plant (or grass) which is the original source of food. Let us take an example to understand the meaning of the Food Chain. In a field with many green plants, a food chain begins. First, insects eat the plants. Then, rats eat the insects.
The plant-insect-bird-hawk system represents a food chain, with each stage referred to as a trophic level. Broadly, trophic levels categorize organisms into producers (plants), primary consumers (herbivores such as insects), secondary consumers (carnivores like birds), and tertiary consumers (top carnivores, exemplified by hawks). Plants start a food chain. They use sunlight as energy to make their food. Plants are eaten by insects. This insect is eaten by a bird. A bird is eaten by a large mammal. When this mammal dies, it decomposes and consumed by bacteria and fungi as food. We, humans eat both plants and animals. We are at the end of food chain. Al-Jahiz, a scientist
Fun Facts about Food Chain for Kids Biology Diagrams
Insects are the most significant link between plants and other animals in food webs, providing an important food source for many animals while also feeding on plants and other animals. As a major part of the global food chain, insects play a vital role in shaping our deserts and contributing to food security. Most food chains start with a green plant, because plants make their own food by photosynthesis. A consumer is a living thing that eats other plants and animals. Food chain basics:
Different food chains may include some of the same organisms. Several consumers may eat the same kind of plant or animal for food. When this happens, the food chain forms a food web. A food web shows how food chains are related within an ecosystem. A food web is similar to a food chain; only bigger. Food webs show how plants and animals are Plants use the sun and nutrients from the soil. Insects eat plants. Rodents eat insects. Reptiles eat rodents. You get the picture. The bigger animals eat the smaller animals. This is the essence of the food chain. The food chain is an important concept for a young child to learn. It helps them see the world as a much larger and more unified place. An art illustration provides a precise visual review of a food chain. Students can draw plants and animals in horizontal, vertical or inside-out sequence to represent the food chain. In horizontal (left to right) and vertical (bottom to top) illustrations, the lowest animal or plant in the chain is kept on the initial point (extreme left or
