*Predation is a communication
among the species in which one
species adopts another species
as food.
*Mainly, a favorable predation
results to spread of predators
and loss of prey.
Types of predation:

Cannibalism:
Cannibalism is clearly predation on
another animal of the same species.
The most common form of
cannibalism is the size-structured
cannibalism; in which the large
species consumes the smaller ones.
For example the dragonfly eating a
its own kind of species and the
bird as well.

Parasitism:
In parasitism, the species gains and
the second species is harmed. The
species that gains is the parasite and
the species that’s getting harmed is
called the host. For example, the
strangler fig growing on tree and the
relationship between a clown-fish and
an anemone.

Herbivory
herbivory happens when an
animal benefits a plant as food.
For example, the
herbivores(insects) eating the leaf
and deer feeding on some leaves.
Pop Culture example:
 Jurassic park!
Scientists took dinosaur DNA
and basically made an amusement
park out of it. After some
accidents, the dinosaurs escaped, and
the carnivores attacked the humans
still at the park. Carnivores = t-rex,
mostly. Prey = human, predators =
t-rex.
The Lion King!
‘Timon’ in the lion king eats the
insects. The insects are the preys
and the predator is Timon.
‘Nala’ tries eating ‘Pumba’.
Nala is the predator and Pumba
is the prey.
Examples of Predation:
The gator chomping
on turtle. The gator
is the predator and
the turtle is the prey.
The heron is eating
the rabbit. Therefore,
the heron is the
carnivore/predator
and the rabbit is the
herbivore/prey.
Predation and population:

Increasing the
population of the prey
will lead to an increase
in population of the
predator because the
predator has more food.

Usually, the prey
population are expected
to decrease because the
predator population
increases
 Natural selection helps
the predators with traits
that make them more
efficient and productive in
gaining the prey. The prey
has advanced traits that
allow them to escape from
the predators.
 Predators have different
kind of techniques to catch
its prey. For example, fast
running speed and sharp
teeth.
