Food Webs

Today in class we received a booklet about food webs. Food webs are just like different food chains put together with a variety of plants and animals.

In the same booklet we learnt about food pyramids. There are different types of food pyramids. They can tell you the mass of the animal or how many animals you need to produce enough energy for the larger animal that eats it. On the bottom of the food pyramid is a producer. ex: grass. Above that are the primary consumers. They are usually herbivores. ex:mouse. Above that are the secondary consumers which can be carnivores or omnivores. ex: snake. On top of the pyramid are the tertiary consumers which are usually carnivores. ex: owls.

After that we did the questions at the end of the booklet.

Next time write will be Shayla.
