Transcript of FOOD CHAINS AND WEBS

Nature's System of Food Chains and Webs by Maiah Bennett Food Chains: Food chains consist of the direct
path in which a certain species or animal preys on
another, from (usually)smallest to largest in an interconnected
chain. Food chains consist of
a variety of animals, and essentially,
every animal is a part of a food chain
(or food web) in
one way or another. AUTOTROPHS: Every food chain has an autotroph as
it's beginning source. Why? Because an autotroph is a
living organism that creates it own energy, and is essential
to sustaining the other organisms in the food chain. Most
autotrophs are plants because they can photosynthesize to make
their own energy and survive. THE SUN The sun is an essential part to a food chain. It works to create
energy for autotrophs and heterotrophs alike, thus sustaining
the food chains and ecosystems here on earth. HETERETROPHS: Heterotrophs are living organisms that consume autotrophs or other heterotrophs. Basically, all animals are heterotrophs and they rely on a food chain to keep them alive. Another name for heterotrophs in consumers, because they are the consumers in the food chain, and make up the primary, secondary, and tertiary consumers in this simple system. The 4 main parts of a food chain:
-producer
-primary consumer
-secondary consumer
-tertiary consumer Tertiary Consumers Food webs are essential to the understanding
and interactions we have in the enviroment, and
often are a passionate subject of enviromentalists
because of their fragility and importance. You can imagine here the huge impact the dissapearance
of just one species would have on the whole food web aquatic habitat food webs mountain food chain producer secondary
consumers forest food webs primary consumers Food Webs Not Otherwise Specified (NOS) THE END.... FOOD WEBS autotrophs and the sun Mice, insects, small mammals, rodents, and other things that feed on mainly autotrophic substances the ones in the food chain that eat the primary consumers and are usually carnivores or omnivores You have probably learned some of the basic ideas
about the food chain in elementary school or junior
high, but the basic pattern is simple. Tertiary consumers are the topmost predatory consumer
in the food chain cycle. They are usually carnivorous, and
dont have any predators above them that prey on them. Some examples of a tertiary consumer would be: -bears
-humans
-eagles
-wolves
-tigers
-hawks
-lions
