Remember:
All living things influence and are influenced by other living things
within a community. No living things exist alone and independently of
others. Some relationships between organisms are beneficial to both
types of organisms. Some relationships are one-sided and some are
harmful.
Animals in general are dependent upon plants for food. In return,
animals give off carbon dioxide which plants use in the food-making
process.
Different relationships exist between organisms in order to satisfy
their needs: food, shelter, protection and others. Plants and animals
live together in order to survive.
Kinds of Relationship
Mutualism- is a kind of relationship wherein both organisms benefit from
each other.
Commensalism – is a kind of relationship in which one organism’s benefits
and the other is not affected at all.
Competition- is a kind of relationship wherein organisms fight with each
other to satisfy their needs to live.
Predation- is a relationship when one organism kills the other for their
survival.
Animals that kill are predators while the victims are called prey.
Parasitism -is a relationship wherein one organism benefits while the other
is harmed.
Parasites get nutrition from another organism while the host is the one
supplying the food.

What happens when the
heart relax?
1. Blood flows into the veins from the heart.
2. Blood flows into the arteries from the heart.
3. Blood flows into the heart through the veins.
4. Blood flows into the heart through the
arteries
37. Why does the heart have to pumps blood?

from the lower to the upper part of the body.
38. A healthy heart beats at the rate of ______.
