1. Amensalism- is the relationship
between two organisms, where one
is hurt.
3.
4. 2. Parasitism
- one organism called
parasite benefits from
the interaction while
harming the other
organism called host.
- Ex:
- Aphids (tiny insects)
on the leaves of plants
- Tapeworms and
hookworms inside the
body of animal or
human
5. 3. Predation
- interaction where the
predator, the bigger or
stronger organism, kills
the prey, the smaller or
weaker animal, for food.
- Ex:
- Hawk and snake
- Zebra and lion
6. 4. Competition
- species contends with members of
its own species for resources.
- Ex: In crowd areas, plants of the
same species compete with one
another for space, nutrients, and
materials needed for photosynthesis
such as water and sunlight. Plants
that lose out grow short and weal
and eventually die.
- Ex: animals compete to obtain food
such as chickens the faster and
stronger will be able to pick up more
grains, while the slower ones will
get lesser grains or none at all.
