Ecology: Interactions and Environments
undefined
ECOLOGY
Introduction
Ecology is about Cause and
Effect
Looks at the
Interaction &
Interdependence
Of organisms to each other and to their
environment.
We have studied
Genus and species
populations
Expanding outward to…
ECOLOGY
“ECO” – “the Environment” /”nature”
“OLOGY”- study of
The study of the interactions
between organisms within a
particular area.
Ecology vocabulary words
:
Individual
– single organism.
Population
– group of individuals who can
mate (species).
Community
– Groups of different populations
within a particular area.
Ecosystem
– Living and non-living things
within a particular area.
Biome
– Groups of similar ecosystems living
together.
Biosphere
– THE WHOLE WORLD
Ecosystem
Self-sustaining
collection of
organisms and their physical
environment
Biotic
– living things
Abiotic
– non-living things
Biome
Major communities that occur
over wide areas on land
Scientists have divided the Earth
into 7-9 major biomes
Climate
– temperature and
precipitation.
Climate dictates biomes.
Major Biomes of the Earth
Niche
-Animal’s role in the ecosystem.
Types of niches:
Herbivore
Omnivore
Carnivore
Predator
Prey
Decomposer
Scavenger
PRIMARY PRODUCERS
In your groups define using two to three words
Eats Producers
Eats consumers and producers
Eats only live animals.
The hunter
The hunted
Break down dead and organic material
Eats animals that are dead/ have been killed
FOOD CHAIN SETS:
In your group
Put your groups set in order
Check another groups set
Draw one of the food chains!
THE ARROW IN A FOOD WEB
SHOWS WHERE THE ENERGY
GOES TO!!
Arrows on the food web show
where the energy goes.
Various Relationships
Mutualism
Neutralism
Competition & Predation
Commensalism
Parasitism
Both organisms benefit
Neither organism benefits
One organism out runs another or takes over an area
One benefits, nothing happens to the other.
Host does not benefit, ONLY parasite does
Match the situation to one of the relationships
Dive into the world of ecology, where organisms interact and rely on each other and their surroundings. Understand the concepts of populations, communities, ecosystems, biomes, and the biosphere. Explore the vocabulary of ecology, from individual organisms to entire biomes. Learn about food chains, niches, and energy flow in ecosystems. Discover the relationships between living and non-living components in nature.

ECOLOGY Introduction
Ecology is about Cause and Effect Looks at the Interaction & Interdependence Of organisms to each other and to their environment. We have studied Genus and species populations
ECOLOGY ECO the Environment / nature OLOGY - study of The study of the interactions between organisms within a particular area.
Ecology vocabulary words: Individual single organism. Population group of individuals who can mate (species). Community Groups of different populations within a particular area. Ecosystem Living and non-living things within a particular area. Biome Groups of similar ecosystems living together. Biosphere THE WHOLE WORLD
Ecosystem Self-sustaining collection of organisms and their physical environment Biotic living things Abiotic non-living things
Biome Major communities that occur over wide areas on land Scientists have divided the Earth into 7-9 major biomes Climate temperature and precipitation. Climate dictates biomes.
Food Chains PRIMARY PRODUCERS In your groups define using two to three words Niche-Animal s role in the ecosystem. Types of niches: Herbivore Omnivore Carnivore Predator Prey Decomposer Scavenger Eats Producers Eats consumers and producers Eats only live animals. The hunter The hunted Break down dead and organic material Eats animals that are dead/ have been killed
FOOD CHAIN SETS: In your group Put your groups set in order Check another groups set Draw one of the food chains! THE ARROW IN A FOOD WEB SHOWS WHERE THE ENERGY GOES TO!!
Arrows on the food web show where the energy goes.
Various Relationships Mutualism Both organisms benefit Neutralism Neither organism benefits Competition & Predation One organism out runs another or takes over an area Commensalism One benefits, nothing happens to the other. Parasitism Host does not benefit, ONLY parasite does
Match the situation to one of the relationships C. A praying mantis insect eats a grasshopper. D. Ox pecker birds picks parasites off the water buffalo for food and the water buffalo have no parasites. A. B. A pack of wolves and a bear fight over a dead deer. Two male lions fight over a female lion. E. F. Spring Wood Tigers vs. Raiders G. H. A tapeworm lives in the intestines of a person, causing illness and weight loss. A butterfly drinks nectar from a flower and the flower gets pollinated. A fungus grows under a tree s bark and causes it to grow slowly. I. L. K Lichens use trees as a place to grow and be protected. The tree is not affected. J. Barnacles attach to the skin of whales where they are able to capture food. The whale is not helped or harmed. Ants milk aphids for honeydew (food) and the aphids are protected from predators by the ants. P. A clown fish lives in a sea anemone. Clown fish guard them from butterfly fish and sea anemones give them a home. Fleas suck blood from a cat. N. You have harmless eyelash mites living in your eyelash follicles M. A blue jay bird pulls an earthworm out of the ground and eats it O. A lion chases, catches, kills, then eats a zebra
