worksheet from EdPlace Biology Diagrams FOOD CHAINS, FOOD WEBS AND ECOLOGICAL PYRAMIDS In an ecosystem, plants capture the sun's energy and use it to convert inorganic compounds into energy-rich organic compounds. This process of using the sun's energy to convert minerals (such as magnesium or nitrogen) in the soil into green leaves, or carrots, or strawberries, is called photosynthesis. For example, in a simple forest food chain, trees and shrubs would act as producers. Rabbits and rodents would be primary consumers feeding on plants. Hawks would occupy the next tier up by preying on herbivores like rabbits. Higher-level consumers like bobcats or coyotes may hunt hawks, sitting above them in the food web. So while hawks are
(C) by showing the reader how each trophic level in a food chain works, starting with the "top" of the food chain (D) by showing the reader how food webs can be disrupted if food chains do not work properly 7 How are food webs more complex than food chains? (A) Food webs are found in more ecosystems than food chains. (B) Food webs are made of In some sense, hawks are at the top of the food chain. However, eagles are larger than hawks, so they occasionally go after smaller hawks and hawk nests. Do hawks eat snakes and lizards? Many hawks eat snakes and lizards. In some places, these small animals make up an important part of their diet. Red-tailed Hawks and Cooper's Hawks are some

The best time to spot Cooper's Hawks hunting is during spring when their young are begging for food. Most hawks will time their nesting strategy with the availability of easy prey like young songbirds. The Swainson's Hawk habitat centers around open field conditions. They love recently tilled fields because insects get pulled up from Consumers found above the tertiary consumers in a food chain, or food web, are called quaternary consumers. They reside at the last trophic level in the food chain and have no natural predators. Thus, in most cases, they are the top predators, or apex predators, in the ecosystem. In the ecological pyramid shown, the hawk is the Quaternary Consumer. A food chain shows how plants and animals get their energy. Here are some of the food chains in this food web: grass โ insect โ vole โ hawk. grass โ insect โ frog โ fox.
The food chain is structured with green plants as producers, toads as primary consumers, snakes as secondary consumers, and hawks as tertiary consumers. Each step shows the transfer of energy from one organism to the next. The chain can be summarized as Green Plants โ Toad โ Snake โ Hawk. Food Web: At each trophic level, there may be many more species than indicated in the table above.Food webs can be very complex. Food availability may vary seasonally or by time of day. An organism like a mouse might play two roles, eating insects on occasion (making it a secondary consumer), but also dining directly on plants (making it a primary consumer).
