Vocabulary
Define Abiotic & Biotic Factors
What is an organism?
An organism is one single animal in an area.
What are all three types of symbiotic relationships?
Mutualism, Commensalism, and Parasitism
A food chain shows one single flow of energy between organisms. A food web shows multiple food chains.
What is competition and give an example.
Competition is when 2 or more organisms are fighting for the same resources.
Example: Trees fighting for sunlight, water, and minerals
Animal Adaptations are any activity or behavior of an animal that helps it to survive (camouflage is an example).
What is a population?
A population is multiple animals from the same species in the same area.
Define Mutualism
Mutualism is a relationship in which both species benefit.
How do the arrows in a food web/chain show the flow of energy? (They point from what to what?)
The energy goes from the prey to the predator.
A bird eats a worm. Who is the predator and who is the prey?
The bird is the predator and the worm is the prey.
Define Homeostasis
Homeostasis is a process by which organisms maintain a relatively stable internal environment (such as sweating).
What is a community?
A community is multiple populations in an area.
Define Commensalism
Commensalism is a relationship in which one organism benefits and the other is unaffected.
The organism on the bottom of the food web are the .......?
Producers
If one species disappears in an ecosystem. What will happen to the rest of the animals?
The whole ecosystem would be thrown off balance.
What is the difference between an organisms habitat and their niche?
A habitat is the place within an ecosystem where an organism lives and a niche is what a species does in its habitat to survive.
What is an ecosystem?
An ecosystem is all of the abiotic and biotic factors in an area.
Define Parasitism
Parasitism is when one organism, the parasite, benefits, and the other, the host, is harmed.
Food webs are filled with predators and their prey.
What happens to the prey population when there is an increase in predators?
The prey population decreases.
Explain limiting factors
Limiting factors are the resources that limit the number of animals an ecosystem can contain and therefore affect the carrying capacity.
Define Carrying Capacity
Carrying Capacity is the largest number of organisms an ecosystem can sustain. The limiting factors in an environment determines this. Limiting factors are the number of available resources in an area.
What is a biosphere?
A biosphere contains all the living and nonliving things on Earth. A biosphere contains all ecosystems.
Pick one symbiotic relationship and give an example.
Examples:
Mutualism - bee and a flower
Commensalism - remora fish and shark
Parasitism - tick and dog
Grass is eaten by a prairie dog. The prairie dog is eaten by a coyote. This is an example of .....
Looking at a graph you notice the population of rattlesnakes declines and the population of rodents increases at the same time.
Based on that information what is the relationship between rattlesnakes and rodents?
