Our goals for this unit
Our goals for this unit

  • I will be able to recognize consumers, producers, and decomposers.

  • I will be able to recognize how changes in populations effect the balance of an ecosystem.

  • I will be able to recognize carnivores, omnivores, and herbivores.

  • I will be able to recognize different types of ecosystems and the organisms living in them.

  • I will be able to analyze both positive and negative effects on ecosystems.

  • I will be able to explain how a food chain and food web interact.

  • I will be able to order animals in a food web/food chain.


Ecosystem
Ecosystem

  • Short for “ecological system”

  • Includes all of the living and nonliving organisms existing together in a particular area

  • Complex set of relationships among the living resources, habitats, and residents of an area; includes plants, trees, animals, fish, birds, micro-organisms, water, soil, and people


Niche
Niche

  • The role of an organism in its habitat


Habitat
Habitat

  • The natural environment where an organism lives


Symbiosis
Symbiosis

  • A close, long lasting relationship between two species


Population
Population

  • All the members of the same type of organism living in the same ecosystem



Predator
Predator

  • An animal that hunts and eats other animals


Prey

  • An animal that is hunted and eaten by a predator




Extinction
Extinction

  • The dying out of all the members of a species


Endangered species
Endangered Species

  • A species that is close to extinction


Pollution
Pollution

  • The addition of harmful things to the environment


Threatened species
Threatened Species

  • A species that is close to becoming endangered


Food chain
Food Chain

  • The description of how energy in an ecosystem flows from one organism to another


Food web
Food Web

  • The description of all the food chains in an ecosystem



Producer
Producer

  • An organism that uses the Sun’s energy to make its own food


Consumer
Consumer

  • An organism that eats other organisms


Different types of consumers
Different types of consumers

  • Carnivore- An animal that eats other animals

  • Herbivore- An animal that eats only plants

  • Omnivore- An animal that eats both plants and animals


Levels of consumers
LEVELs OF cONSUMERS

  • Primary consumer- an animal that gets all its energy from plants (herbivore)

  • Secondary consumer- an animal that eats primary consumers (carnivore)

  • Tertiary consumer- an animal usually at or near the top of the food chain; eat other consumers (carnivores or omnivores)



Decomposer
Decomposer

  • An organism that breaks down dead plants and animals into simpler materials that enrich the soil


Energy pyramid
Energy Pyramid

  • Shows how energy moves to each level of an ecosystem


Test prep
Test Prep

  • Which would have the same effect on a zebra population as increasing the number of lions in the habitat?

  • The grass-eating insects die from disease.

  • No fires occur during the dry season.

  • Antelopes and wildebeests move into the area.

  • Trees are uprooted during a summer storm.


Test prep1
Test Prep

  • A cat eats a mouse. Which is the cat?

  • Parasite

  • Population

  • Predator

  • Prey


Test prep2
Test Prep

  • A tick is an animal that takes blood from its host. Which type of symbiosis does this describe?

  • Commensalism

  • Mutualism

  • Niche

  • Parasitism


Test prep3
Test Prep

  • Two species of birds share an island and depend on the same food source. Which would likely happen if food became scarce?

  • The birds would all fly away.

  • Both birds would become extinct.

  • The island’s bird population would decrease.

  • The smallest bird species would become extinct.


Test prep4
Test prep

  • Which of these is a predator/prey relationship?

  • A mouse eats a seed.

  • A plant gets energy from the Sun.

  • A spider eats a cricket.

  • An owl uses a cactus for a home.


Test prep5
Test prep

  • Which is a role of lions in an ecosystem?

  • Lions help keep the population of trees under control.

  • Lions help keep the population of zebras under control.

  • Lions help keep the population of wolves under control.

  • Lions help keep the population of grasses under control.


Test prep6
Test Prep

  • A town used pesticides to control mosquitoes in the

  • area. Scientists later observed that the population of

  • one type of bat had decreased. Which is the BEST

  • conclusion you can draw from this information?

  • People overhunted the bats.

  • This type of bat ate mosquitoes.

  • The bats’ habitat was destroyed.

  • The bats died from disease spread by the mosquitoes.


Test prep7
Test Prep

  • The zebra mussel was introduced into a lake ecosystem. Within a few years, the zebra mussel population soared, and it showed no sign of declining. Which conclusion can you draw?

  • The mussels will soon become extinct.

  • The mussels are not adapted to freshwater.

  • The mussels play a vital role in the lake’s ecosystem.

  • The mussels have no natural predators in the lake.


Test prep8
Test Prep

  • In the last several years, the number of rabbits in a

  • Mississippi forest has remained the same. Which of the

  • following would MOST LIKELY cause the number of rabbits

  • to decrease?

  • Plant more tress in a forest.

  • Increase the size of the rabbits’ habitat.

  • Increase the number of decomposers in the habitat.

  • Introduce carnivores, such as hawks and bobcats, into the habitat.
