What is ecological succession?
process by which the mix of species and habitat in a given area changes over time
Give one action human do that increases global warming?
burning fossil fuels for electronics, cars, electricity ect
What is the 3 type of Symbiosis?
Mutualism
Commensalism
Parasitism
All the energy in a food web/on earth comes from
The sun
What is Ecology
Ecology is the study of the relationships between living organisms, including humans, and their physical environment;
what is a niche?
the role an organism plays in a community
Give one action humans can take to slow global warming?
use alternative sources of energy(wind, solar ect.) reduce and recycle materials
What is symbiosis.
Relationship in which 2 species live closely together.
Which part of a food web has the most energy and why?
Autotrophs(Producers) they make their own and the energy comes directly from the sun
Differnences between Biome and Biosphere.
Biome is a collection of different ecosystem that share similar climate conditions,Biosphere contains all the different biome.
Carnivores are usually found where on a food pyramid?
top trophic level
What is one negative effect of using pesticides crops on crops and give one alternative to the use
can get into water supple due to runoff and can use natural predators of the pest
Give an example of Mutualism
Clownfish and sea anemones
What part of the food web gets the least amount of energy but the most toxins
the top of the pyramid
What is the 2 types of factors exist in an ecosystem and an example of each?
Abiotic factor
biotic factor
in a predator prey relationship when the population of predators decreases over time the prey population will what
decrease
Deforestation is the cutting down of trees for human use one negative effect is soil loss what is another negative effect of this
increase in atmospheric CO2, destruction of habitats
What is commensalism & give an example
One organism benefits the other is unharmed/unaffected
remora and a shark
Draw an energy pyramid and label each part with the type of organisms (Producers, carnivores, herbivores and omnivores)
producers at bottom, then herbivores(primary consumers) , omnivores(secondary consumers), carnivores (tertiary consumer)
What is a food chain?explain.
food chain is a one way transport of energy,the transport of energy shows in arrow.(in only one chain)
What is the difference between a community and an ecosystem?
a community is all the biotic factors in a given area and the ecosystem is both the biotic and abiotic factors
What is an invasive species and why are they a threat to ecosystems and give an example
an organism that is introduced to an environment that they do not natural occur in, can outcompete native populations ex: boa constrictors in FLorida, Lantern FLY in NY, zebra mussels in NYS
Explain what is "Parasitism"
One organisms lives on or inside another organisms and harms it.
Who are decomposers, why are they important and give an example?
organisms that breakdown dead, decaying organisms. Recycles nutrients back into environment
mushrooms
funguses
molds
What does an ecosystem need to be self-sustaining and give one abiotic limiting factor and one biotic limiting factor on a population
constant source of energy, ability to change energy into organic molecules and cycle minerals and nutrients between organism and environment
light, temperature and food availability and predation
