Definitions
The study of the relationships between organisms and each other, in relation to their environment.
What is ecology?
True or false? Tertiary and top predators are the same thing?
False.
Tertiary means 3rd level consumer. Top predators do not have any predators themselves - they could be at any trophic level.
This type of animal eats a variety of foods.
What are omnivores?
What is the sun?
Which trophic level should have the highest biomass?
An organism that can produce its own food.
What is an autotroph?
A group of one species living in the same place at one time is called what?
A population
Nonliving parts of the ecosystem
Abiotic factors
This happens when two organisms of the same species are fighting for the same resources.
Intraspecific competition
Why does the pyramid of numbers not always accurately show ecosystems?
It shows the number of organisms without taking into account their size (a tree would be able to support more organisms than a blade of grass)
The role, or way of life of a species within its environment.
What is a niche?
Relationship between bees and flowers
What is mutualism?
Biosphere, biome, ecosystems, community, population, and species
What are the levels of ecology?
What does a food chain end with?
What is the apex or top predator?
What is 3,500,000 g/km^2?
Only one species benefits without harming or benefitting the other.
What is commensalism?
Interspecific competition
Each step or level in a food web/chain (shows energy transfer)
What is a trophic level?
What level would a cow be in a food chain?
How much energy is lost between each tropic level? What is this rule called?
What is 90% is lost? This is the 10% rule (10% of energy is passed up the trophic levels)
It covers large areas and is characterized by the climate and the types of plants and animals that are found there.
What is a biome?
What are the levels of organization starting with organism to the largest?
What is organism, population, community, ecosystem, biome, biosphere?
Hawk and owls occupy a different _____.
Owls hunt during the night, hawks hunt during the day. If two species occupy the same _________, they would constantly be in competition.
What is an example of a niche?
If a food chain is
Grass --> Crickets --> Frog --> Snake --> Hawk
what would happen to each of the other populations if the population of frogs doubled?
Snakes would increase then hawks would increase
Crickets would decrease and that would make the grass increase.
If an ecosystem starts with 845,000 kcal of energy at the producer level, how much energy is available for the Tertiary consumer?
What is 845 kcal of energy?
