Eco 101
Define global warming.
What is global warming?The accumulation of CO2 in the atmosphere causing the temperature of the earth to increase.
Define Ecosystems.
Biotic and abiotic factors in a specific region.
Define an abiotic factor.
A non-living factor affecting species abundance and dispersal (Temperature, Sunlight, Wind, Soil Type, etc)
An organism that produces eggs is considered....
Sexual
Who wrote Ms. Luna's favorite Body system song?
Meg thee stallion
Define Symbiotic Relationships
Relationships between different species in the same ecosystem.
The goal of this level of ecology is to understand factors affecting population growth, density, and size. It also involves studies of species interactions such as predation and mutualism.
What is population ecology?
Which determines broad species distributions: climate or weather?
CLIMATE
Weather, because it is short term, is more likely to impact an individual organism rather than the entire population.
An ascaris nematode feeds on nutrients in the intestines of a pig.
Parasitism
What other fields can ecology be linked to?
Genetics, physiology, behavior, paleontology, evolutionary biology
How does biodiversity relate to ecology?
When a population has reached the maximum number based on resources.
Carrying Capacity
Solar radiation is needed because....
it is the initial source of energy
A tiger affects the dispersal of gazelle by consuming newborn young.
Predation
Living factors that affect species abundance and dispersal is known as a...?
Biotic Factor
One human activity that is thought to be a major contributor to global warming and an explanation of how it may contribute to the problem.
Multiple correct answers, but must mention CO2 being added to the atmosphere.
Abiotic factors in ecosystems will impact what other levels?
community, population, and organism.
What is the major environmental factor limiting the numbers of autotrophs at great depths in the ocean?
Light!
An ox-bird eats the parasites of the skin of a cow.
Mutualism
How can humans *decrease* their contributions to global warming?
Multiple correct answers, but CO2 must be *removed* or *not added* to atmosphere.
Explain why many ecologists would agree with the statement that “A rainforest ecosystem is more stable than a city.”
Rainforests have more variety or organisms than a city, which adds to the stability.
List the four levels of ecology from smallest to largest.
Organism, population, community, ecosystem.
Give five examples of an abiotic factor.
1) Soil Type
2) Temperature
3) Climate
4)Water
5)Wind
Mosquitos suck blood from the surface of a cow's skin
Parasitic
What is an introduced species?
Species brought into regions by human actions either intentionally or unintentionally.
