For tundra plants and animals, survival is not just about battling the harsh environment of this biome, but is equally about being a part of its complex food web. 2) Explain some functions/processes of your ecosystem including one nutrient cycle and one food chain. Biomagnification, also known as bioamplification or biological magnification, is any concentration of a toxin, such as pesticides, in the tissues of tolerant organisms at successively higher levels in a food chain. Background Information on Food Chains and Food Webs. In a freshwater aquatic ecosystem like a pond, the organisms in the food chain include algae, small animals, insects and their larvae, small fish, big fish and a fish-eating bird or animal (Figure 8.4). Every food chain starts with energy from the Sun. 3) Give two examples of species interactions (predation, competition, mutualism, etc.) Green plants are autotrophic, meaning they create their own food using a chemical reaction called photosynthesis.During photosynthesis, plants take carbon dioxide from the air and water from the ground through their roots, which react to produce glucose and oxygen. This energy gets transferred through producers to primary, secondary and tertiary consumers to decomposers and finally returns to the environment. Some animals eat plants and some animals eat other animals. A food chain shows how this energy flow occurs. For example, a zebra eats grass, and the zebra is eaten by the lion. As per the trophic levels, here is an example of a food chain: Grass (Producer) → Goat (Primary Consumer)→ Man (Secondary Consumer) Often we encounter animals consuming dead and decaying matter, such chains that begin with the consumer eating dead organic matter are known as Detritus Food Chain (DFC). The fragile food chains of tundra support some of the most amazing species on the planet, including the likes of gray wolves, polar bears, snowy owls, and Arctic foxes. In this lesson we are going to talk all about food chains and food webs in the environment. Food chain, in ecology, the sequence of transfers of matter and energy in the form of food from organism to organism. Food chain is a linear sequence of organisms which starts from producer organisms and ends with decomposer species. A food chain shows how each living thing gets its food. Each link in this chain is food … For example, a simple food chain links the trees and shrubs, the giraffes (that eat trees and shrubs), and the lions (that eat the giraffes). This lesson will define what a food chain represents, go through specific examples of food chains, and compare and contrast a food chain with a food … A food chain in a grassland ecosystem may consist of grasses and other plants, grasshoppers, frogs, snakes and hawks (Figure 8.3). What is a food chain easy definition? Food chain - definition With the help of solar energy, producers produce food. This completes the energy cycle. Food web is a connection of multiple food chains. Learn more about food chains in this article. Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant. A food chain is a flow of energy from a green plant (producer) to an animal (consumer) and to another animal (another consumer) and so on. Food chain follows a single path whereas food web follows multiple paths. The food chain looks like this: Grass - Zebra - Lion; Food chains are a simple look at how sunlight is made into energy by plants through photosynthesis, then how that energy is transferred from animal to animal after eating the plants. From the food chain, we get to know how organisms are connected with each other. Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant. Food is energy. Food chain , in ecology, the sequence of transfers of matter and energy in the form of food from organism to organism.
