Opening Prayer

Heavenly Father , grant me each day the desire to do my best. To grow physically, mentally and

morally To be kind and helpful with my classmates and teachers. To be honest with myself and with others. Help me to be a good sport when I lose

How do organisms interact with each other and with their

environment?

Living things or organisms interact with other living things and with non living things or the physical

environment. And there are several ways of the interactions among

livings.

Some are beneficial for one organism but harms the other. And

some are beneficial for the two organisms that are involved.

Group 1

Types of Ecological Relationship:

1. Commensalism- Type of relationship where one organism

benefits from the other which neither benefits nor harmed

Examples of Commensalism

1. Epiphytic plants growing on a tree*epiphytes- plants that needs other plants/trees for support

2. Remora fish attached on bigger fish like shark and whales

Group 2

2. Mutualism- A type of relationship where two species

benefit from each other

Other Examples of MutualismLichen- combination of alga and fungus

African Crocodile and Plover

Group 3

3. Parasitism- . A relationship where an organism (parasite) gets its nutrients from a living host that

was harmed by the interaction

Other examples of Parasitism

Lice on human head

Insect larva

Tapeworm- lives in the gastrointestinal tract of some animals

Group 4

Predation- An interaction where an animal kills and eat the

other.The most common type of

ecological relationship*Predator- the animal that eats the

other animal*Prey- the animal that was eaten

Other Examples of Predation

Group 5

Competition- A relationship that occurs when two organisms

compete for the same resources

Other Examples of Competition

What are the different types of ecological relationship?

How does an organism interact with another

living thing in each of the ecological relationship?

Which type of relationship do you commonly see in your

environment? Can you cite examples?

Employees like factory and construction workers were paid by their employer in exchange of their services. The employer benefits in this relationship through the service of the workers. The employees benefit too because of the money that they could get

B. A student who keeps on asking/borrowing for paper, pens, crayons, assignments etc instead of buying or working on his/her own.
