Hierarchy of Life
Abiotic things are not alive, and biotic things are alive
True or False: People are mammals
True
What is the difference between IMMIGRATION and EMIGRATION?
Immigration is when animals move INTO a population. Emigration is when animals move OUT OF a population.
True or false: Both species in a competitive relationship are benefitted
False: In a competitive relationship, both species are negatively affected because both are fighting for the same thing which makes their lives harder
What is an ecosystem?
An ecosystem is made up of all the biotic (living) and abiotic (non-living) things in an area that interact with each other.
What is an INDIVIDUAL
An individual is one living thing
True or False: Frogs are reptiles
False: Frogs are amphibians
If a wolf population had a high birth rate one year, would the population grow or shrink?
Grow
True or false: Foxes hunting mice is an example of predation
True
What does Carrying Capacity mean?
It is the maximum number of life an ecosystem can support over a long period of time
True or False: All the elephants living in Africa and all the elephants living in Asia make up ONE population
False: A population is a group of individuals of the same species living in the same area whereby they can interact with each other.
What is an example of a fungi?
Mushrooms
If a drought and a lot of plants dried up, would the plant population be growing or shrinking?
Growing
What is the difference between MUTUALISM and COMMENSALISM?
In mutualism, both species in the interaction are benefitted. In commensalism, one species gets a benefit while the other is not affected.
What is biodiversity?
Biodiversity is the variety of life in an ecosystem
What is the difference between a COMMUNITY and an ECOSYSTEM?
A community is all of the living things living in an area. An ecosystem is all the living AND non-living things in an area.
What are the four types of PHYLA we talked about?
Animals, Plants, Fungi, Protists
Birds in Population 1 ate a bunch of fruit with seeds in them. The birds then flew over Population 2, and pooped the seeds out, so the seeds would grow in the new population. What would happen to the fruit populations in Population 1 and Population 2? (Growing or Shrinking?)
Population 1: Might shrink, might stay the same
Population 2: Grow
What type of interaction is the following:
Trees provide shade to rodents in hot summer months
Commensalism
The rodents are benefitted, and the trees are not affected
Why are keystone species important?
Their niche affects their ecosystem in a big way. Without keystone species, the ecosystem would be very negatively affected.
What are some abiotic things that can be used to describe a biome?
Temperature, Precipitation, Rock formations, etc.
What are the taxonomic classification levels from most general to most specific?
Level, Kingdom, Phylum, Class, Order, Family, Genus, Species
The birth rate of rabbits in a forest is half as high as the rabbits' death rate. Is the rabbit population growing or shrinking?
Shrinking
What type of interaction is the following:
The roots of trees and the roots of fungi grow together. Tree roots pick up water to feed itself and share with the fungi, and the fungi roots pick up nutrients to feed itself and share with the tree
Mutualism
Both the fungi and the trees are benefitted by this interaction.
In a meadow, the limiting factor for flowers is the number of bees because there are not a lot of bees that can pollinate many flowers. However, one summer, a new colony of bees moves into the area. How would this affect the limiting factor and the flower population?
The limiting factor would increase, so more flowers could live in the ecosystem
