Explain the three different symbiotic relationships.
Parasitism - One organism benefits while the other organism is harmed (+,-).
Commensalism - One organism benefits while the other organism is not affected (+,0).
Mutualism - Both organisms benefit (+,+)
The study of organisms and their interactions within the environment is known as ___.
Ecology
Is soil present at the start of primary succession? If not, describe what is present.
No. Rock, ash, etc. is present.
What is a biomass pyramid, and what does it represent in an ecosystem?
A biomass pyramid shows the total mass of living matter at each trophic level in an ecosystem. It indicates that biomass decreases from producers to top consumers, reflecting how energy is lost at each level.
What are Autotrophs and Heterotrophs? Explain their roles?
Autotrophs are mainly producers that capture energy and convert it to food
Heterotrophs are mainly consumers that need to eat for energy
Explain the difference between Intraspecific Competition and Interspecific Competition.
Intraspecific Competition is competition within the same type of species while Interspecific Competition is between different types of species.
Describe what a population is?
multiple individuals or organisms of a single species that live within a particular geographic area.
Describe the difference between Primary and Secondary Succession?
Primary - occurs from "scratch", may take thousands of even ten thousand years
Secondary - Occurs after a disturbance that does not obliterate an existing community, often takes just hundreds of years
What happens to the energy as it transfer from trophic level to trophic level??
•Organisms next on the chain only receive 10% of the energy form the previous level
•Other 90% is used or “lost” as heat
Double Point Quesiton: What is the hawk classified as in this food chain? (List; Grass -> Cricket -> Frog -> Snake -> Hawk)
Apex predator
In a community, organisms have a habitat and a niche. State the difference between Habitat and Niche?
Habitat is a natural home or environment of the organism [Address]
Niche is the role or function of an organism in an ecosystem [Job]
Describe what a community is?
two or more populations of different species that occupy the same space at the same time
What is the first type of species that establishes themselves?
Pioneer species
In a pyramid of energy which organism should have the largest amount of energy?
The producer
What is Chemosynthesis and where does it occur?
- Chemosynthesis is the act of making food from chemicals
-It occurs in some bacteria (deep sea vent/bacteria)
A bee drinks nectar from flowers, while spreading pollen from plant to plant. This is an example of what symbiotic relationship?
Mutualism
Describe the difference between abiotic and biotic factors. List one example of each.
Biotic - living (ex. plants, etc.)
Abiotic - nonliving (water, etc.)
Describe what a climax community is?
A stable, mature ecological community with little change
Define primary productivity and discuss its importance in ecosystems.
-Primary productivity is the rate at which producers create organic matter through photosynthesis.
a. It is vital for ecosystems as it provides energy for consumers.
What is the chemical formula for photosynthesis
CO2 + H20 -> C6H12O6 + O2
In a spruce tree environment, there is a Bay-Breasted Warbler and a Yellow-Rumped Warbler. The Bay-Breasted Warbler feeds in the middle part of the spruce tree while the Yellow-Rumped Warbler feeds in the lower part of the tree. Is this an example of the species having a different niche or environment?
This is an example of the species having different niches in the same habitat
A large area that has a particular climate and distinct plants and animals is called a __.
Biome
What is the end result of succession in ponds/lakes?
Water dries up and eventually is a forest or grassland
