Habitats and Niches

Within an ecosystem, organisms
occupy habitats and niches.

What are these and what is the
difference between these?
© 2004 Plano ISD, Plano, TX
Habitat

A location in the environment where an organism can
grow and survive

Includes all of the physical and biological resources
available to a species
© 2004 Plano ISD, Plano, TX
Niche

Refers to the way an organism fits into and survives in
its ecosystem

Includes not only where it lives but what it does in its
environment

No two species occupy exactly the same niche

Niche is determined by physical characteristics of
organism, its behavior, how it reproduces, etc.

Clown fish

Clown fish are small in size; the smallest is 10 cm and largest is 18 cm long, and they
don't believe in traveling too far, as compared to whales, dolphins or sharks, in
search of whatever awaits in the distant places. It can be found in the shallow
waters, especially in the regions, where the water temperature is in range of 24 to
28 degree Centigrade, and the sloping sea bed boosts the growth of corals.

The shallow water allows the sunlight to reach the seabed and thus, promotes
growth of the zooplankton, which are tiny animals. The presence of the zooplankton
invites copepods and isopods which are scavengers by nature. The clown fish feed on
the copepods, zooplankton, isopods and the algae present in the shallow waters. The
lagoons formed because of the coral reefs are sheltered from the rage of the seas
and function ideally as the habitat for this fish.

The clown fish prefer the company of sea anemones which inhabits the deep as well
as shallow waters. It can be found living in the warmer waters of the Pacific Ocean
and Indian Ocean

In a group of clown fish, there is a strict dominance hierarchy. The largest and most
aggressive female is found at the top. Only two clown fish, a male and a female, in
a group reproduce through external fertilization.

Clown fish lay eggs on any flat surface close to their host anemones. In the wild,
clownfish spawn around the time of the full moon. Depending on the species, clown
fish can lay hundreds or thousands of eggs. The male parent guards the eggs until
they hatch about six to ten days later, typically two hours after dusk.

Research Questions
1.
Draw a diagram of an ecosystem near where you live .
Label the factors “biotic” or “abiotic.”
2.
Give two examples of how plants and animals affect
their environment
3.
Describe how temperature, light, and soil affect an
ecosystem
4.
Think of a forest ecosystem. Now imagine that a large
amounts of dust and ash into the air, blocking out
sunlight. How might the forest ecosystem be affected
if the sunlight is blocked out for a day?
