All of the organisms that live together and interact with one another make up the ______ part of the environment; the ______ part of the environment consists of the nonliving elements such as water, soil, light, and temperature.
biotic; abiotic

Where do producers receive their energy? What process do they complete with this energy and for what purpose? The product of the process comes in what form?
The sun Photosynthesis to make their own food Glucose (sugar)

Discuss the predator/prey relationship. Give an example of a predator and its prey.
A predator is an organism that eats another organism known as the prey.
100
What is evaporation? What must be present for it to occur? What step is it in the water cycle?
When the sun is present over a body of water, it is the change of a substance from a liquid to a gas/water vapor
100
What are the two types of succession?
Primary Succession Secondary Succession
200
Which of the following has the highest level of environmental organization? A. Ecosystem B. Community C. Population D. Biosphere
D. Biosphere
200
Name the three types of consumers and give an example of each.
Herbivores, Carnivores, Omnivores
200
Define competition. Give an example.
When two organisms or multiple populations compete/fight over the same resource.
200
Give an example of how water is very important to the life of organisms besides the need to hydrate/drink it.
Water regulates body temperature
200
Define a pioneer species. What is the pioneer species during primary succession?
The first species to live in an area Lichens
300
What is a population? Give an example.
A group of organisms of the same species that live in a specific geographical area
300
Give the correct definition of a scavenger. What type of organism is it? Give an example.
An omnivore that feeds on the remains of dead plants and animals. Example= vulture
300
What is mutualism? Give an example of a mutualistic relationship.
A relationship between two species in which both species benefit. Example= bee and a flower
300
What is combustion?
The burning of a substance such as wood or fossil fuels
300
Describe primary succession. What is the starting point and end result? It is dependent on the strength, growth, and formation of what?
When something grows for the very first time Begins with exposed rocks and lichens End result is a climax forest Soil
400
An ecosystem is a community of organisms and the _______ ____________.
abiotic environment
400
Discuss what the purpose of an energy pyramid is (what does it show?). Diagram an energy pyramid with appropriate organisms in each level.
A triangular diagram that shows an ecosystem's loss of energy. Predators Herbivores Producers
400
Tapeworms are segmented flatworms that attach themselves to the insides of the intestines of animals. Tapeworms get food by eating the animal's partly digested food, which deprives the animal of food. Identify which organism is helped, harmed, or not helped/not harmed and which kind of relationship is occurring.
Helped= flatworms Harmed= animal Relationship= Parasitism
400
Describe the processes of photosynthesis and respiration. Which types of organisms complete which process? Elaborate on the relationship of the two different groups of organisms and their related process.
Plants use Carbon Dioxide during photosynthesis to make sugars/food. Their byproduct is Oxygen. Mammals use Oxygen during respiration and their byproduct is Carbon Dioxide. Both groups of organisms have a mutualistic relationship because both are dependent on each other for survival.
400
How does secondary succession differ from primary succession? Describe this process.
Secondary succession is when something regrows after a natural disaster occurs.

Place the levels in order from GREATEST to LEAST: 1. A group of grey wolves 2. A bald eagle 3. The Biosphere 4. Wolves, rabbits, field mice, and grass 5. A forest including oak trees, owls, spiders, squirrels, streams, and deer
3. The Biosphere 5. A forest including oak trees, owls, spiders, squirrels, streams, and deer 4. Wolves, rabbits, field mice, and grass 1. A group of grey wolves 2. A bald eagle

Discuss the "Circle of Life". Be sure to include all levels of organisms and the main source of energy.
Sun gives energy to Earth Producers use the sun's energy Consumers eat producers/other consumers Decomposers break down organisms after death Energy is returned to producers
500
What is a limiting factor and carrying capacity? How do the two relate? Give an example.
Limiting factor= a resource that is so scarce that it can limit the size of a population Carrying capacity= the largest population that an environment can support The carrying capacity is a direct reflection of the amount of limiting factors that are available for the population.
500
Diagram the water cycle. Be sure to include ALL parts!
Evaporation, condensation, precipitation, run-off, groundwater, water collection
500
Describe biodiversity. What is an advantage of having a high level of biodiversity?
The variety of species that are present in an area The more diverse an area is, the stronger it is against invasions.
