1. Food chains and food webs

2. carnivores
A carnivore is an animal that gets food from killing carnivores have to hunt down and kill other animals they require a large amount of calories. This means that they have to eat many other animals over the course of the year. The bigger the carnivore, the more it has to eat. You should make sure that you have many more herbivores and omnivores than carnivores.ling and eating other animals

3. Herbivores
A herbivore is an animal that gets its energy from eating plants, and only plants. Omnivores can also eat parts of plants, but generally only the fruits and vegetables produced by fruit-bearing plants. Many herbivores have special digestive systems that let them digest all kinds of plants, including grasses.

4. Omnivores
An omnivore is a kind of animal that eats either other animals or plants. Some omnivores will hunt and eat their food, like carnivores, eating herbivores and other omnivores. Some others are scavengers and will eat dead matter. Many will eat eggs from other animals.

5. Detritivores
An organism that feeds on and breaks down dead plant or animal matter, returning essential nutrients to the ecosystem. Detritivores include microorganisms such as bacteria and protists as well as larger organisms such as fungi, insects, worms, and isopod crustaceans. In a food chain, detritivores are primary consumers

7. What are food chains?
A food chain shows the feeding relationship between different living things in a particular environment or habitat. Often, a plant will begin a food chain because it can make its own food using energy from the sun. Also, a food chain represents a series of events in which food and energy are transferred from one organism in an ecosystem to another. Food chains show how energy is passed from the sun to producers, from producers to consumers, and from consumers to decomposers.

8. Important facts about food chains
In a food chain each organism obtains energy from the one at the level below.
Plants are called producers because they create their own food through photosynthesis3
Animals are consumers because they cannot create their own food, they must eat plants or other animals to get the energy that they need.

10. Different Types of food webs

11. What is food web?
A food web is a diagram of the links among species in an ecosystem – essentially who eats what. A food chain shows only the organisms that contribute to the diet of the top consumer.

12. Important facts about Food web
The base of a food web is occupied mostly by vegetation (producers) and fine organic debris (decomposers).
Herbivores (primary consumers) and carnivores (secondary consumers) occupy the higher levels.
Omnivores occupy an intermediate level in the food web.
Food webs are complicated by the fact that many species feed at various levels.

13. Difference between food chain and food web
FOOD CHAINS FOLLOW A SINGLE PATH AS ANIMALS EAT EACH OTHER.
FOOD WEBS SHOW HOW PLANTS & ANIMALS ARE INTERCONNECTED BY DIFFERENT PATHS.
A food chain only shows one food relationship of a biotic element.
A food web only shows the orca eating a ringed seal.
A food chain shows how each living thing gets its food.
A food web is a series of related food chains displaying the movement of energy and matter through an ecosystem.

14. Why is the sun so important to food chains?
This is because plants the only autotrophs on earth (meaning the only ones who can prepare there own food) prepare their food by a process called photosynthesis for which sunlight is an important component and as we know all living beings directly or indirect depend on plants for their food thus sun is very important for the food chain

15. What is the importance of algae in the marine food chain and food web?
Algae, a microrganism (a tiny organism) serves as food for small aquantic creatures such as krill and shrimp, and these small organisms serve as food for larger animals such as whales and manitees. Basically, algae serves as food for small animals, and these animals serve as food for large animals, which keeps the food chain balanced, with the provider, in this case the algae, at the bottom, and the primary (manitees) and secondary (whales) consumers are at the middle and the top.

16. Importance of food chains and webs?
Food chains and webs ensure that one particular species cannot become too large and therefore destroy the species it feeds on, creating a massive inbalance. This means that every creature has a predator and/or environmental threats so their population cannot increase to an amount that is unhealthy for the surounding ecosystem.
