Your factor is a quadrat
Name one biotic factor that affects the distribution of plant and animal species.
humans, competitors, predators, parasites
What is a niche?
specialized habitat of an organism
What is mutualism?
What is the zone of intolerance?
area where no individuals of a species live
What is the competitive exclusion principle?
two species competing for the same resources will not both be able to survive. die or move
List and describe one sampling technique when using quadrats.
percent coverage-You see how much of the square is covered with the organism of interest.
individual sampling-You count how many of each individual plant there is within the quadrat.
Name two things that are included in a niche.
space and territory, nutrition and feeding habits, interactions and relationships with other organisms, reproductive habits, role
Define and give an example of parasitism.
Relationship where one species benefits and the other is harmed. Ex: dog and flea, tapeworm and person, etc.
What's the formula for calculating net production?
NP=GP-R (net=gross-respiration)
What is an example of secondary succession?
forest fire
State the method used to determine the distribution of a species between two or more types of terrain. This method can also be used to determine the distribution of species in accordance with another abiotic factor.
transect line
What's the difference between a fundamental and a realized niche?
fundamental niche is bigger, fundamental is all the places an organism could live (potential)
What is predation? What trophic levels can these organisms occupy?
One organism hunts and feeds on another. Primary consumer or above.
Which biome is represented by II and why?
Desert because high temperature and low rainfall.
What's the difference between primary and secondary succession?
primary succession occurs where there was no life, primary succession has no dirt
What are the 6 factors affecting the distribution of species of a plant?
temperature, water, light (intensity/wavelength), soil pH, soil salinity, mineral nutrient availability
Explain with an example from both the animal and plant kingdom what a keystone species is.
-
1. Frugivores eat fruit while folivores eat foliage.
2. Frugivores can be in mutualistic relationships while folivores are usually parasitic.
Draw and label a Gersmehl diagram.
Watson check
How do you make soil?
Begin with lichens. Lichens die and rock weathers. Build up over time of nutrients and dead organic matter which is broken down.
Water is one factor that affects the distribution of animal species. Using an example, outline three other factors that can also affect animal distribution.
We talked about tigers and whales. Can be any example but factors can be: temperature, breeding sites, food supply, territory
List the three types of niche partitioning, and give an explanation of one.
spatial, temporal, morphological
List and define the two types of competition, and give an example of each.
interspecific-between different species like lions and hyenas fight over food
intraspecific-between the same species like giraffes fighting over mates
Identify the biome represented by the diagram and explain why the sinks are their respective size.
Water is an excellent solvent of other polar molecules. Most macromolecules are polar and water can break these down to enter the cell. Water is also an excellent medium. Blood is most common transport medium in animals; blood is mainly made up of water. Blood is a transport for red blood cells, white blood cells, and variety of dissolved molecules.
What's the difference between an open and closed ecosystem? What's a disadvantage to each?
A closed ecosystem will have the matter remain in the system. In an open ecosystem, matter can leave via migration, harvesting, etc.
