It consists of an interaction between two individuals of the same species or different species that is beneficial for both.

Commensalism

Association between two organisms in which one benefits and the other obtains neither benefit nor harm.

Parasitism

It is one of the most widespread life strategies in the Animal Kingdom, with at least 20% of animal species being parasites of other organisms. There are taxa only composed of parasitic beings, such as viruses and acanthocephalans (parasitic worms).

Example: Some examples of parasites are tapeworms, fleas, and barnacles.

2. Recall

Zebra mussels negatively impact ecosystems in many ways. They filter out algae that native species need for food and they attach to--and incapacitate--native mussels.

how are plants being growing in an area after a forest fire?

The heat from the fire causes the fire-activated seeds to germinate and the young plants can take advantage of the fact that the rest of the surrounding plant life was destroyed in the fire. The cones of the Lodgepole pine are sealed with a resin that melts with fire, which then causes the seeds to be released.

how is a population different from a community?

A population is a group of the same species living in the same area. A community is a group of different species living in the same area.

Many people are moving to the deserts. How can this displacement affect the ecosystems of the rivers that flow through these deserts?

Illegal hunting and trade of plants -mainly cacti- and vertebrates. Inadequate policies and inefficient law enforcement create perverse incentives for agriculture and water extraction.

Your class has been asked to help improve the natural environment of your community. What are three things that you and your class could do?

Avoid burning trash, leaves and other objects, as well as campfires in the woods or in the middle of town. Water plants at night or very early in the morning, when the sun takes longer to evaporate the water. Reuse the water you collect from watering and washing vegetables to water your plants or garden.
