Figure 3. This food web shows the interactions between organisms across trophic levels in the Lake Ontario ecosystem.
17 de feb. de 2023 · Typically, a food chain is represented by a diagram where arrows show the direction of energy and nutrients flow. Many herbivores eat grass, and deer can eat other plants besides grass. Even a tiger can eat many types of animals and plants. Thus, each animal is part of multiple food chains. All interconnected to make a food web.
Food Chains. A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another; the levels in the food chain are producers, primary consumers, higher-level consumers, and finally decomposers. These levels are used to describe ecosystem structure and dynamics.
12 de mar. de 2023 · A food chain always starts with a producer. This is an organism that makes its own food. Most food chains start with a green plant, because plants can make their food by photosynthesis. A living ...
