Predation, Mutualism, Commensalism, or Parasitism
Commensalism Commensalism is a relationship between two living organisms where one benefits and the other is neither harmed nor helped.
The clownfish lives among the forest of tentacles of an anemone and is protected from potential predators.
Some birds live among cattle to eat the insects stirred up as they walk. One example are egrets who hunt for insects near a grazing animal's mouth.
One animal attaching itself to another for transportation such as barnacles attach to shells or whales or a shrimp riding on a sea slugs. shrimp riding on a sea slug barnacles on whale’s tail and clam
One species uses a second organism for housing such as small mammals or birds that lives in holes in trees or orchids which live in trees. Orchid in rainforest Venezuela
Parasitism One organism, usually physically smaller of the two (the parasite) benefits and the other (the host) is harmed
Ticks and fleas that live in a host animal's fur bite the animal and drink its blood are parasites.
Insects such as mosquitoes feeding on a host are parasites.
Vines such as Kudzu growing on Trees
Tomato Hornworm with Wasp Eggs
Tapeworm or Hookworms living in Host's Gut
The roots of the Owl Clover are partly parasitic on the roots of other desert wildflowers.
Mutualism Both species benefit from the interaction.
Flowers and their Pollinators (examples: Bees and hummingbirds gather nectar and spread pollen.)
Birds and mammals eat berries and fruits while the plant benefits by the dispersal of it seeds.
Algae and Fungi > Lichen - Alga gets water and nutrients from the fungus and the fungus gets food from the algae.
Cleaners eat insect pests from the skin of animalsCleaners eat insect pests from the skin of animals. (ex: Egyptian plover cleans giraffes and buffaloes)
Many herbivores such as cows, sheep, deer, horses and rabbits depend on bacteria that live in their stomachs to break down the plant material.
Coral Reefs- The corals get food and the algae get protection.
Predation one eats another (Herbivores eat plants. Carnivores eats animals.)
Relationships In Ecosystems How Species Interact With Each Other Chapter Eight Section Two.
Symbiotic Relationships. Symbiosis Symbiosis is a close ecological relationship between the individuals of two (or more) different species.
Population – group of individuals of the same species
Interactions of Living Things Ecology 3. Species Smallest grouping of living based on characteristics – Must be able to produce offspring that can reproduce.
SYMBIOSIS: relationships in nature. Definition of Adaptation Characteristics that allow an animal to survive in its environment. These characteristics.
Community Interactions Community: Many species interacting in the same environment Three types of interactions: – Competition – Predation – Symbiosis.
Interactions Name that Relationship!. Name That Relationship! Acacia ants live on the bullhorn acacia tree, which provides the ants with food and shelter.
Symbiotic Relationships. What is symbiosis? What it means: Two organisms that live together Temporarily or for a longer time At least one of the organisms.
A particular species of a unicellular organism inhabits the intestines of termites, where the unicellular organisms are protected from predators. Wood.
By Abraham Zetino. Mutualism is when both organisms benefit from the relationship. Ex: A rhino is not irritated because birds are eating fleas/bugs.
Warm Up Can you think of examples of relationships where both people/ organisms benefit? Can you think of examples of relationships where one organism.
Types of Species Interactions. Competition Trees in the rainforest competing for light Desert plants competing for water.
WANTED: Interactions Amongst Organisms. Mutualism, a relationship between two species in which both species benefit. The ox pecker bird, which is seen.
THE NATURE OF ECOLOGY Ecology is a study of connections in nature.
Population – group of individuals of the same species living in the same area, potentially interacting. Community – group of populations of different.
