Introduction

My name is Sebastian Flores and I study at Colegio Menor and they assign me a project. In the project I am going to use PowerPoint, the Internet blogger, and I am going to do a PowerPoint about interactions among living things. My 4 sub topics are what is predation, what is symbiosis, what and which are defense strategies. I am going to use Microsoft Excel, power point, and this blogger spot. At the power point program, I am going to do a 10 slide show to show people about interactions among living things. At Microsoft Excel I am going to do a graph and a table to show the rates of my topic.

What is symbiosis?

A symbiotic relationship is a relationship between two entities which is mutually beneficial for the participants of the relationship.

There's mutualism, which is when both organisms benefit, commensalism, when one benefits and the other isn't affected, parasitism, which is when one benefits and the other is harmed, and competition, is the struggle between both people, animal, or plant. Some examples of symbiotic relationships are:

-mutualism: When an insect needs to feed on flower pollen and the flower needs to pollinate its self to reproduce.

-commensalism: When an owl lives in the branch of a tree but the tree isn’t harmed or doesn’t harm.

-parasitism: When a dog has parasites in his stomach or fleas on his fur and the parasites/fleas are harming the dog but the dog can’t do something.

-competition When 2 wolfs fight for a rabbit, for food.

What is predation?

Predation is an interaction between organisms in which one organism captures and feeds upon another called the prey. The predators usually the larger and stronger of the two. Predators are always either carnivores or omnivores. The prey might typically be a herbivore, but some predators feed on anything they can capture, including other predators.

Some examples. -A wolf chasing a rabbit for food. -An owl flying over a rat for food. -The grizzly bear at a river finding fishes for diner. -A tiger and a zebra at the wild jungle.

What and which are defense strategies?

A defense strategies are when an organism displays a wide array of adaptations that help the avoid becoming a prey. There are five different "strategies" for organisms to be able to develop and don't become a prey. There is Mimicry, False coloring, Protective covering, Camouflage, and Warning coloring.

Mimicry: It's like it says, when an organism imitates another animal than can be harmful when he is going to be eaten.
Ex. When a caterpillar is going to be eaten by a bird, he mimics to a snake so the bird will not eat him.

False coloring: When certain organism changes of color to see like a big animal. Ex. When a moth is at a tree and is dark, so a bird will eat the moth, so the moth changes color to see like an owl. Protective covering: When an animal is threatened to be eaten, the organism will roll to it's "shell" so it will not be eaten by predator.
Ex. When a lion will eat a pangolin, the pangolin will act fast will roll in to it's hard shell.

Camouflage: When an organism changes of color; like the background to be camouflage with it's environment for predator to don't see him.
Ex. When you are at the forest passing by and you see a walking leaf, it will be a walking leaf.

Warning coloring: It's when an organism develops an ability to be poisonous with it's skin, so warning colors like a hard blue or red or yellow will be warning colors.
Ex. When at your pond you see a very rare frog, it is red and black. It will be a very poisonous frog that might kill you.

PD. People native from the "oriente" use poisonous frog skin to put it at the top of a dart to kill animals.
