Abiotic
How many characteristics of life are there?
Ecological relationships such as mutualism, commensalism, and parasitism are called ____________ relationships
symbiotic relationships
Overlapping food chains make a ________.
FOOD WEB
WHat organisms are at the bottom of the energy pyramid?
Producers
What does a food web show?
A food web shows you what eats what, Predator and prey relationships
Living things found in an ecosystem
Biotic factors
commensalism
Energy in a food web all start with the ______ .
THE SUN
Primary consumers are typically what type of eaters?
Herbivores
identify 2 secondary consumers
Fox, Owl, Frog, BIrd
Give 3 examples of abiotic factors
Rocks, dirt, clouds, sun, water, air, soil, etc.
This photo is an example of what ecological relationship? and why?
Mutualism
IDENTIFY THE SECONDARY CONSUMER
MOUSE
Secondary consumers are typically what type of eaters?
omnivores
Identify 2 primary consumers
rabbit, mouse, grasshopper
A flood causes a stream to change course, what type of change is this?
Abiotic change
What ecological relationship does this photo represent?
Commensalism
Explain how the disappearance of the Snake would affect its predator and prey
The kite population would decrease because it would be without food, and the mouse population would increase
At which level of the energy pyramid is the least amount of energy available?
the top!
If the population of birds were to decrease, what population would increase?
the Grasshopper
List the characteristics of life.
Growth and development
Ability to reproduce
Made up of 1 or more cells
Maintain homeostasis
Gets and uses energy
Responds to stimuli
Explain in detail why symbiotic relationships are a very important part of ecosystems
ecological relationships are important for ecosystems because species rely on one another for survival.
Explain what happens if an organism in a food chain dies off. How does that effect the food chain?
The food chain will be thrown off, some predators will be without food and that animals prey population will rise do to the lack of predators
As energy is moved up the energy pyramid, what happens to the amount of energy being transferred?
Energy is lost during each transfer so apex predators receive less energy than animals lower on the food chain
If the population of Fox were to increase due to the large amounts of prey, what would happen? (Think about our predator vs. prey game outside!)
The rise of the fox population will actually be their downfall. When populations rise, there eventually wont be enough food to go around- then the population will decrease due to lack of food.
