What is a population? Give an example.
A group of the same type of organism in an area.
Example: Lion Pride
What is a top consumer in food webs?
Organisms that do not get eaten by anything else. They are the top predators.
How does water return back to the atmosphere?
Evaporation and Transpiration
What is Ecology?
The study of the interactions between organisms and the environment.
What is a species?
Similar organisms that can reproduce and produce fertile offspring.
Which organisms get the MOST energy? Which get the Least amount of energy?
MOST = Eagle
LEAST = Trees and Grass
What is precipitation?
When water returns back to earth (gas to liquid) in the form of rain, snow, sleet, or hail.
What is a producer?
An organism that makes their own food, usually using the sun.
Plants!
What is the difference between a community and an ecosystem?
Community - Involves the LIVING things in an area
Ecosystem - Involves the LIVING AND NONLIVING things in an area.
What would happen to an ecosystem if all of the plants died out?
Everything would eventually die due to lack of food.
How is nitrogen gas turned into a form that organisms can use?
Bacteria - Nitrogen fixation
What is the difference between herbivores, carnivores, and omnivores?
Herbivores - Eat only Plants
Carnivores - Eat other consumers (eat meat)
Omnivores - Eat Both plants and meat (animals)
What is a Biome? Give some examples.
A large area with the same climate, and similar types of plants and animals.
Desert, Tropical Rainforest, Tundra, Savannah, Grasslands, Deciduous Forest
Which organisms are carnivores, herbivores, and omnivores.
Carnivores = Eagle, Snake, Frog
Herbivores = Deer, mouse, grasshopper
Omnivores = None
Producers = Trees and Grass
Which cycle does not EVER enter the atmosphere because it does not have a gas form?
Phosphorus
Give one primary consumer, one secondary consumer and one tertiary consumer.
Primary (first) = Mouse, grasshopper, deer
Secondary (second) = frog, Eagle, Snake
Tertiary (third) = Eagle
List the levels of organization from smallest to largest.
Individual (organism), Population, Community, Ecosystem, Biome, Biosphere
What would happen to the ecosystem if all the frogs died out?
- Plant population would decrease due to increase in grasshoppers.
- Eagles would not have as much to eat so population might drop.
How do humans impact the carbon cycle.
Burn fossil fuels, cut down trees, car fumes, respiration
