Ecology Unit Test Flashcards
What two organisms are mainly known to be decomposers
Bacteria and fungi
What is the role of the decomposer in an ecosystem
Decomposers breakdown dead plants and animals they also break down the waste of other organisms
If decomposers weren’t an ecosystem the plants would not get essential nutrients and dad matter and waste would pileup
Name the type of ecological relationship
As insects fly around and feed off of the nectar of flowers they carry pollen from one flower to another helping the plants reproduce
Mutualism
Heartworm is an animal that can live in the heart of dogs the warm gets nutrition but the leaves the dog malnourished
Parasitism
Algae lives on the back of some turtles. The algae get transportation and a place to live the algae have no effect on the turtle
Commensalism
At night I was hunting mice birds and other small animals
Predation
Termites eat I’m glad but they cannot digest it themselves. Organisms living inside the termite guy just the parts of the wood for them this provides food for both organisms
Mutualism
What is the word for organisms ecological roles or job within an ecosystem
Trophic level
A snake lives in the forest eat small animals such as birds and lays eggs in nests that are buried in the ground identify the snake habitat
The rain forest
Biotic or abiotic?
Water
Abiotic
Biotic or abiotic?
Nitrogen in a living organism
Abiotic
Biotic or abiotic?
Soil
Abiotic
Biotic or abiotic?
Animals
Biotic
Biotic or abiotic?
Trees?
Biotic
Biotic or abiotic?
Nitrogen in the air
Abiotic
Biotic or abiotic?
Bacteria
Biotic
Biotic or abiotic
Carbon dioxide in the atmosphere
Abiotic
Biotic or abiotic?
Fungi
Biotic
What organisms are responsible for removing carbon out of the atmosphere and how?
Trees and plants use photosynthesis to chemically convert the carbon dioxide to carbon-based sugar molecules
During what processes carbon dioxide removed from the atmosphere?
Photosynthesis
Define evaporation
Changing of the liquid into a gas often under the influence of heat
Define condensation
The conversion of a vapor or gas to a liquid
Define pprecipitation
Water that falls to the ground as rain snow etc.
Define collection/run off
Water from rain or snow that flows over the surface of the ground into streams
Define transpiration
Transpiration is the process where plants absorb water to the roots and then give off water vapor through pores in their leaves an example of transpiration is going to plant absorbs water in its roots
What is the difference between evaporation and transpiration
If operation occurs in water becomes paper from bodies of water transportation occurs when water leaves a plant as vapor
Name a type of succession that would take place it’s a fire destroyed forest
Secondary succession
Name a type of succession that would take place is a volcano erupted
Primary succession
Describe the 10% rule
It states that energy when passing from prey to predator is only concert rated at about 10%. For example, when do you eat the grass only 10% of the energy that the grass received from the sun is passed onto the dear
Is a rabbit a heterotroph are in autotroph
Rabbits are heterotrophs
What are the characteristics of living things
Growth Reproduction Metabolism Stimuli DNA or genetic material Cell organization Evolution
Give an example of a producer
Grass
Give an example of a consumer
Dear wolves Bears grasshoppers hocks
What is one major difference between a producer and consumer
Producers are autotroph’s and consumers are heterotrophs
Give me example of a herbivore
Deset
Give an example of a carnivore
Wolves
Give an example of an omnivore
Bears and rats
Give an example of a scavenger
Vultures and raccoons
Give an example of a decomposer
Bacteria and fungi
What is a detritivore
An animal that feeds on dead organic material especially plant detritus
Give an example of a detritivore
Earthworms
Three reasons why decomposers are vital to an ecosystem
Breakdown animal waste and dead organisms and released free nutrients back into the ecosystem
Break down the dead organisms to where the scavengers can eat the organism that was broken down without the decomposers scavengers will die
Breakdown organics into nutrients which can be used by living organisms to create new life
An example of mutualism
Digestive bacteria and humans
The bacteria stays alive the humans get get help with the process of digestion
An example of commensalism
Birds and trees
An example of parasitism
Wasp larvae and Catapillar
Tick and dog
What is an example of predation
Tigers hunting buffalo
why is bio diverse city important
Biodiversity boost economic productivity were each species, no matter how small, I’ll have an important role to play. For example, a large number of plant species needs a greater variety of crops. Greater species diversity is insures natural sustainability for all lifeforms
They help keep our lives in balance and regulate the climate
What are the three main components of the water cycle
Evaporation condensation and precipitation
When it rains on land one of three things will happen to that water named those three possibilities
Infiltration
Run off
Transpiration
What is the relationship between photosynthesis and respiration in the carbon cycle?
Photosynthesis converts CO2 into O2 , Respiration does exactly the opposite bonding carbon with O2 to make CO2
Name three ways humans impact the carbon cycle
Urbanization
Forest fire
Burning fossil fuels
