Nonliving
What is abiotic

a measure of biodiversity for an area by dividing the total number of species by the total number of individuals
What is the biodiversity index
100
If the mouse population was drastically reduced in this ecosystem, this change would have the greatest negative effect on which of these other species? Why?
What is the snake since according to this partial food web it only eats the mouse.
100
What is biodiversity, how do humans affect it, and how does it affect humans?
What is Biodiversity underpinning the health of the planet and has a direct impact on all our lives. Put simply, reduced biodiversity means millions of people face a future where food supplies are more vulnerable to pests and disease, and where fresh water is in irregular or short supply

What is the percentage of energy GAINED as it moves from producer to primary consumer to secondary consumer?
What is 10%
200
The variety of life
What is biodiversity
200
Put this food web of organisms into a trophic level diagram
What is written by teacher
200
How should the populations of grass, grasshoppers, frogs, and pythons be distributed so that all populations are sustainable?
What is a small amount of pythons, a medium amount of frogs, and large amounts of grasshoppers and grass
200
How do organisms obtain and use the matter and energy they need to live and grow?
What is a living organism either making its own food or depending on others to make food for them. For example green plants produce their own food from a process called photosynthesis. They use the chloroplasts in their cells to capture energy in sunlight.
200
A relationship between two species in which one species benefits and the other is neither helped nor harmed.
What is commensalism
300
any biotic or abiotic component of the ecosystem that controls the size of a population
What is a limiting factor
300
The capacity to do work.
(Hint: Most of this is used by organisms comes from the sun)
What is Energy
300
Explain the relationship between the Red Squirrel and the Gray Squirrel.
What is the introduction of the gray squirrel into the ecosystem reduces the population of red squirrel's population overtime
300
How do organisms interact with the living and nonliving environments to obtain matter and energy?
What is organisms interacting with the nonliving parts of their ecosystem to get food, energy, and other resources that help them survive. The nonliving parts of the ecosystem are called abiotic factors. Sunlight: Sunlight provides energy that plants and certain bacteria absorb to make their own food.

Describe what would make up the community of coral reef
What is clown fish, jelly fish, seaweed, etc.
400
an introduced species that has a negative impact on an ecosystem
What is an invasive species

Biodiversity Index, what does it all mean?
What is the Biodiversity Index measuring how diverse each animal group is in their schoolyard. The closer the number is to 1, typically the more diverse the group of animals. A lower value for the Index may be due to the fact that there is a large number of the same species (a high species evenness). A higher value for the Index may be due to many different species, with only a few of each of the species present (a high species richness).
400
Photosynthesis is a process by which plants prepare their own food in the presence of water, chlorophyll, sunlight, and CO2. What is a limiting factor of photosynthesis based on the graphs above?
What is...Photosynthesis is affected by light, temperature, water, and CO2.
400
How do matter and energy move through an ecosystem?
What is matter and energy are being transferred from one form to another. Nutrients and living matter are passed from producers to consumers, then broken down by decomposers.
400
a sequence of organisms that eat one another in an ecosystem
What is a food chain
500
a system of interacting organisms and nonliving factors in a specified area
What is an ecosystem
500
The quality of not being harmful to the environment or depleting natural resources, and thereby supporting long-term ecological balance
(Hint: Can last or maintain itself over a long period of time)
What is a sustainable ecosystem
500
Diagram a model that shows how photosynthesis cycle matter and its flow of energy into and out of an organism.
What is...
500
What happens to ecosystems when the environment changes?
What is.... if organisms cannot adapt to the changes in their ecosystem, they may move to another location. If they will not move, the species may become threatened, endangered or extinct.

How are biodiversity and an ecosystem's health related?
