Kinds of Ecosystems
What are two types of Terrestrial Ecosystems?
Forests, Grasslands, Tundra, Deserts, Rainforests, etc.
What do we call an organism that makes its own food, usually using sunlight?
Primary Consumers or First-level consumers
Why do predators need other animals in an ecosystem?
For food or energy.
What shows how energy moves from one organism to another in an ecosystem? (Think simple)
Food Chain
What is the difference between abiotic and biotic factors?
Abotic is nonliving. Biotic is living.
What is the name of organisms who eat other living things for energy?
Consumers
What three groups are needed to make a complete food chain?
Producers, Consumers, and Decomposers
What human activity often leads to the destruction of animal habitats?
Construction, or building.
What type of consumer eats only plants?
Herbivores
Which lists animals that live in an aquatic ecosystem?
A. black bear, deer, vole
B. ducks, turtles, amphibians
C. panthers, monkeys, snakes
D. prairie dogs, bison, grasshoppers
B. ducks, turtles, amphibians
In a food web with grass, grasshoppers, moss, and mushrooms, this organism is a consumer.
Grasshopper
Why might you see more wild animals like deer and coyotes in cities or neighborhoods?
Their habitat or ecosystem is decreasing in size.
Koalas may become extinct.
This is a trait or behavior that helps an organism survive in its environment.
Adaptations
What type of ecosystem has the greatest amount of biodiversity?
Oceans
A crow eats a dead animal for energy. What type of consumer is this?
Scavenger
In a food chain, foxes are consumers of rabbits and mice. If the mice population suddenly decreases, what will most likely happen to the number of foxes?
The number of foxes will decrease due to lack of food.
What can happen to animal populations when humans destroy habitats?
There is an increase in endangered species.
What is the name of the ecosystem that contains both fresh, and salt water?
Estuary
Which best describes what makes one ecosystem different from another?
A. the amount of sunlight, rainfall, temperature, and species types
B. the amount of animals, oxygen, plant life, and pollution
C. the amount of carbon dioxide, oxygen, water, and soil
D. the amount of soil, water, buildings, and humans Kinds of Ecosystems LS.5.2.1 Formative 25-26
A. the amount of sunlight, rainfall, temperature, and species types
How are consumers and decomposers connected?
Consumers provide nutrients/energy for decomposers.
The following represents an energy pyramid:
Level 1 --> Level 2 --> Level 3 --> Level 4
Which level are producers located in?
Level 1
In crowded communities, organisms often do this to survive.
Compete for food and resources.
What happens when harmful substances like chemicals or trash enter air, water, or land and harm living things?
Pollution.
