Population and Energy Flow Flashcards
How can you determine if an animal in a food web is part of multiple levels?
If that animal has arrows from two different levels pointing to it.
For example:
The duck has an arrow from bullrush and the snail therefore it is a first level and a second level
Symbiosis
The interaction between two organisms from different species.
There are three types of symbiosis: Mutualism, Commensalism, and Parasitism.
The four limiting factors we discussed in class
Food
Water
Shelter
Climate
(the same as the necessities of life)
Consumer
An organism that gets its energy by eating/consuming other organisms
What defense mechanism is represented by the picture?
Mimicry
The four factors that can change a population size.
Birth Rate - makes it increase
Immigration - makes it increase
Death Rate - makes it decrease
Emigration - makes it decrease
cooperation vs symbiosis
copperation is two or more organisms of the same species. Symbiosis is between two different species
Population
All of the organisms of one species in one specific area
For xample the population of squirrels in Severna Park vs the population in Norfolk, VA
Predator
An animal that hunts adn kills another animal for food.
Chemical Energy
The energy store in the bonds of a chemical compound.
For example - the energy stored in food.
Amount of energy that is transferred from one level of the energy period to the next.
10% of the level below
Prey
an animals that is hunted adn killed for food
Scavenger
Animals that eat dead animals that have been killed by another animal
What defense mechanism is represented by the picture?
False Coloring
example of mutualism
tick bird and gazelle
cleaner fish and a moray eel
bee and flower
