Interactions in an Ecosystem
Predation
Competition
Whale Shark eats
plankton and small fish
Hawks and fox eat
mice.
Interactions in an Ecosystem
Parasitism
Mosquito sucking
blood from
animals.
Mutualism
Oxpecker Bird eats
ticks and parasites.
Beasts get pest control
Interactions in an Ecosystem
Mutualism
Remora sharks have an
adhesive disk on their
dorsal surface, with the
help of which they
attach themselves to
whales and then, clean
the whale’s skin and
feed on the remains
from the whale's food.
Interactions in an Ecosystem
Commensalism
• "The pearlfish
uses the sea
cucumber for
a hide-out
from
predators.
The pearlfish
will live in the
sea
cucumber’s
anus, backing
into the hole
tail-first so its
head can
stick out."
Interactions in an Ecosystem
Commensalism
• Glass shrimp, which
are almost
completely see
through, will attach
to the chocolate
chip sea star and
take on its
coloration. This
helps the shrimp
camouflage itself so
it is not eaten by
predators."

Activity/Lab
Energy Flow in Ecosystems
Page 134
Nearly all of the
energy that drives
ecosystems
ultimately comes
from the sun.
At each level,
called a trophic
level, about 90%
of the energy is
lost.
Solar energy, which
is an abiotic factor, by
the way, enters the
ecosystem through
the process of
photosynthesis.
Primary consumers only obtain a fraction of the total solar
energy—about 10%—captured by the producers they eat. The
other 90% is used by the producer for growth, reproduction,
and survival, or it is lost as heat.

• Many & diverse types of
ecosystems. There are seven
major types.
• Location usually dependent

amount of precipitation
• The 7 Major Biomes
1. Tropical Rain Forrest
2. Savanna
3. Desert
4. Temperate Grasslands
5. Deciduous Forests
6. Coniferous Forests
7.Tundra
Ocean
(Aquatic)
• Most of Earth (~75%)
• 40% of all photosynthesis
occurs in oceans.
3 types
• Shallow ocean waters
• Deep ocean water
• Deep ocean surface.
• Photosynthetic
plankton is base of
food chain.
• Only occurs in Deep
ocean surface &
Shallow ocean
ecosystems
• No photosynthesis
can occur in deep
ocean because light
cannot penetrate
deeply into water.
Fresh Water
(Aquatic)
• Smallest Ecosystem
~ 1.8% of earth's surface
• Support many species
of life including fish,
amphibians, insects and
plants.
• Base of food-web is
found in freshwater
Plankton (small
microscopic organisms)
• Home to amphibians,
reptiles and almost 41%
of world’s fish species.
• Faster moving water
typically supports greater
biodiversity than the
slow moving water of
pools (fast = more dissolved oxygen)

Marine Ecosystems and Media
Marine Ecosystems - interdependence of all
organisms living in the ocean, in shallow
coastal waters, and on the seashore.
Abiotic Factors
water
light
temperature
pressure
dissolved gasses
salinity
Biotic Factors – broken into zones because
the biotic factors differ depending on
location
Marine Trophic Pyramid – See example
Homework: Review New Notes about the
Cycles and Marine Ecosystems

Marine Ecosystems
Estuaries - an area in which fresh water from a river
mixes with salt water from the ocean.
– Very productive ecosystems…constantly receive fresh
nutrients from the river and from the ocean
– The Chesapeake Bay is the largest estuary in the United
States. It produces large amounts of seafood each year,
supports many species of wildlife, and provides
recreation for millions of people.
– Ecosystems of the bay are threatened by several
environmental problems (pollution, runoff, etc.)
Marine Ecosystems
• Coral Reefs - limestone ridges built by tiny coral
animals, which slowly accumulate and form coral
reefs.
– Supports life of thousands of species of plants and
animals; one of the most diverse ecosystems on Earth.
– Corals need clear and warm salt water for
photosynthesis…typically found in shallow, tropical seas.
– Fragile to pollution and human activities. Pollution,
change in water temperature, and runoff can devastate a
reefs ecosystem (27% in the world are currently in
danger)
Ecosystems and the Media
Does the media always accurately portray
ecosystem interactions?
Watch the following video clips and determine the following:
1) What interactions have you observed within the living
things in the environment?
2) Mutualism? Commensalism? Parasitism? Predator/Prey?
Symbiotic?
3) Are these relationship and interactions realistic?
Why or why not?
