Species Interactions
Describe the altruistic seeming relationship between a bee and her queen
A bee will g it ensures her gens will be passed on ive her own life for the queen becusegive her own life in order to ensure her genes are passed on through the queen
Describe the rule of 10 (2 parts)
10 Percent of energy is passed down from trophic level to trophic level. The rest is lossed as heat
Define Niche, and describe 2 examples
Niche is an organism's tole in its environment. Plants act as primary producers as they make organic material from inorganic materials etc...
Contrast Abiotic and Biotic factors, and come up with one example of each.
Biotic, living factors. Tree
Abiotic, nonliving factors, climate
What is the main goal of life?
To survive, reproduce, and pass on one's genes. (Or maintain family genes)
List 5 niches of the food web
Producer, Primary consumer, Secondary Consumer, Tertiary Consumer Quaternary consumer (rare)
Define and provide one example for the following- Primary Producer, Primary Consumer, Secondary consumer
Primary producers are autotrophs that obtain their energy from non organic sources. Primary consumers eat producers, secondary consumers eat primary consumers.
Identify when carrying capacity takes place after exponential growth. Explain why this occurs.
Carrying capacity occurs when resources run too thin to maintain an ever growing population. This occurs as most resources are limiting biotic factors.
Gut Bacteria provides what for an organism?
The ability to break down certain materials and to take in energy that would otherwise be unavailable
A plant starts with 100 kilocalories of energy. How much energy would be available to the secondary consumer?
1 kilocal of energy
Define Specieation
The creation of one or more species from an already existing species
A barrier that prevents fertilization of the egg in a species that will eventually diverge into new species
Prezygotic barrier
Contrast between Mutualism, Commensalisms, and Parasitism
Mutualism- ++
Parasitism- + -
Commensalism- +0
Justify why a bear would gain more energy from eating berries and plants, as opposed to a human being.
Answer mentions rule of 10, and how eating lower trophic levels will grant access to more energy
Describe one relationship in the animal kingdom that is mutualistic.
Student identifies what a mutualistic relationship is, as well as properly describing a relationship that is beneficial to both members of the relationship
An initial population of badgers starts the year at 300 badgers per square mile. by May of this year they have grown to 450 badgers. What was their average growth rate per month? (assuming they had linear growth?
10%
Describe 1 example for each of the following terms- Mutualism, Commensalism, and Parasitism
mutualism- humans and dogs
Parasitism- leeches
commensalism- tree frog seeking shelter on a tree
Contrast the diversity of the following communities.
A- has 7 species present, all with 20 organisms
B- has 4 species present with the following numbers, 2,2, 134, 2
Species A has a more diverse community, as it has a higher richness of species, as well as a more even abundance of each species.
When 2 organisms share a niche, competition usually occurs between those species. Identify 2 alternatives that could occur that contradicts this claim
Niche Partitioning, Migration
In the Carbon Cycle, too much CO2 will acidify the ocean. How does this affect marine life?
Acidification can harm the physical structure of organisms, as higher pH breaks down Calcium Carbonate, which many organisms use to build their shells. Acidification can also harm microbiota, which will harm the food chain.
