  • Ecology and Types of InteractionsRemember: Ecology is the study of interactions between organisms and their environment.

  • Ecology and Types of Interactions

    I. Ecologists have described three main ways that species and individuals affect each other.

  • A. CompetitionWhen two or more individuals or populations try to use the same limited resource.

  • A. CompetitionThese two trees are competing for root space, sunlight, and water.Competition is bad for both because if one doesnt receive enough resources, it may die.

  • 1) Limited resource - scarce resources like water, food, space, even mates.

  • 2) Carrying Capacity the number of individuals that an environment can support; controlled by competition for limited resources and predator/prey interactions.

  • What has caused the population to level out?Carrying Capacity

  • B. Predator and PreyThe interaction of one individual eating another.

  • Prey1. Prey- organism that is eaten. Prey adaptations include advantages that help prey hide themselves or escape predators.

  • Predator2. Predator- organism that eats the prey. Predator adaptations include advantages over the prey that help predators catch their prey.

  • Prey Adaptations

  • i. Mimicry - the ability of some creatures to imitate others, either by sound or appearance for protective purposes

  • ii. Camouflage - Protective coloring or another feature that conceals an animal and enables it to blend into its surroundings.

  • iii. Warning Coloration Bright colors and patterns that warn potential predators of the potential risk that would come from attacking or eating it.

  • Predator Prey Relationships

  • Consumers are Divided into Five Categories----------------- consumer that eats plants.

  • Consumers are Divided into Five CategoriesHerbivore consumer that eats plants.---------------- consumer that eats animals.

  • Carnivore

  • Consumers are Divided into Five CategoriesHerbivore- consumer that eats plants.Carnivore- consumer that eats animals.---------------- consumer that eats both plants and animals.

  • Omnivore

  • Consumers are Divided into Five CategoriesHerbivore- consumer that eats plants.Carnivore- consumer that eats animals.Omnivore- consumer that eats both plants and animals.------------------ animals that feed on the bodies of dead animals.

  • Scavenger

  • Consumers are Divided into Five CategoriesHerbivore- consumer that eats plants.Carnivore- consumer that eats animals.Omnivore- consumer that eats both plants and animals.Scavengers- animals that feed on the bodies of dead animals. ____________ - organisms that get their energy by breaking down the remains of dead organisms.

  • Decomposers- Organisms that get their energy by breaking down the remains of dead organisms.

  • C. Symbiosis A long-term association between two or more species.

    There are three types we will be discussing

  • MutualismA relationship in which both organisms benefit from each other.

    Cleaner shrimp cleaning a zebra moray eel. Bacteria found in human large intestines.

  • 2. CommensalismA relationship in which one organism benefits and the other is unaffected.

    Remoras attach themselves to sharks and feed of the scraps of food that the shark leaves behind.

  • 3. Parasitism One organism benefits while the other is harmed.

    The parasite is the organism that benefits in the relationship.

    The host is harmed

  • Evolution is tied to the need for energy.

  • A. Evolution - the process in which organisms produce offspring which are biologically different than their ancestors, yet are more capable of surviving and producing offspring in the environment.
