Ecosystems Dynamics
Bottom of the feeding pyramid; largest group
Primary producers (plants)
DAILY DOUBLE
A trait that enables an animals to blend in with its environment or to hide in plain sight.
What is camouflage?
An abiotic factor?
water, soil, air, etc.
Areas of water with very low levels of oxygen
What is a dead zone?
Organisms in second trophic level
primary consumers and herbivores (cows, deer, rabbits, etc.)
Animals that use warning coloration may have distinctive patterns, contrasting colors, or bright colors.
What is warning coloration?
End result of succession
What is climax community?
DAILY DOUBLE
When an ecosystem has been disturbed but soil and organisms remain.
What is secondary succession
DAILY DOUBLE
Do populations of different species of birds that live in the same community compete?
What is interspecific competition. Birds could be competing for food or habitat.
Nest building, reflex, migration, etc.
What is examples of innate behavior?
Some plants need fire to to germinate, how would this give plants an advantage in succession?
After a fire, these would be among the first plants to germinate and begin the process of succession.
After a volcanic explosion what would be some of the first things to grow back?
What is lichens or mosses
A chain among organisms in a stream.
What is algae -> stream invertebrates ->fish ->birds
Arrow needs to point away from the energy source.
Why would competition between members of the same species be greater than competition between individuals of different species?
They use the same kinds of resources.
DAILY DOUBLE
With no greenhouse effect on Earth, what would happen to temperature on Earth?
The Earth would be much colder.
DAILY DOUBLE
The prey population grows larger when this happens
What is the top consumer is removed from the food web?
How animals contribute to the nitrogen cycle.
Animal waste decomposes and adds nitrogen (ammonia) to the ground. Dead animals will also decompose, and due to nitrogen fixation, nitrogen will be added to the soil.
Organisms in the food pyramid from bottom to top
What is the primary produces (plants), herbivorous consumers (herbivores), 1st level carnivorous consumers (primary consumers), 2nd level carnivorous consumers (secondary consumers), top carnivores
How might cutting down a forest affect the greenhouse effect?
Since less carbon dioxide is taken form the air, the greenhouse effect could be increased because of higher CO2.
