|
Name six abiotic features.
|
Water, sunlight, air, soil, temperature, climate.
|
|
|
What are the three gases that compose the largest part of air?
|
Nitrogen (78%), Oxygen (21%), Carbon Dioxide (.03%)
|
|
|
What gas do plants use in phosynthesis?
|
Plants take in carbon dioxide for phosynthesis and release oxygen.
|
|
|
What do animals breathe in?
|
Animals breathe in oxygen and breathe out carbon dioxide.
|
|
|
What is the oxygen cycle?
|
Producers (plants) take in CO2 and release O2. Consumers breathe in O2 and breathe out CO2
|
|
|
How much water does a human body contain?
|
Human bodies are about 70% water. Most organisms are 50 - 95% water.
|
|
|
What is soil?
|
Soil is a mixture of mineral and rock particles, the remains of dead organisms, water, and air.
|
|
|
What is the ultimate source of life on earth?
|
The sun provides the energy source for most life
|
|
|
What happens during photosynthesis?
|
Producers turn light energy into chemical energy that is stored in sugar molecules (glucose). This stored energy is passed on to consumers when plants are eaten.
|
|
|
What is the Energy cycle?
|
Light energy through photosynthesis is converted to chemical energy in glucose to mechanical energy.
|
|
|
What is the temperature range of most living organisms?
|
Most organisms can survive only if their body temperature stays within 0degrees C to 50 degrees C.
|
|
|
What is climate?
|
An area's average weather conditions over time including temperature, rainfall, or other precipitation and wind.
|
|
|
How does energy flow?
|
Energy can be converted from one form to another. Consumers obtain energy by eating other organisms.
|
|
|
What does a food chain show?
|
A food chain is a way of showing how matter and energy pass from one organism to another.
|
|
|
What are the steps in a food chain?
|
Producers are always the 1st step. They make the food. Herbivores are 2nd. Carnivores are 3rd.
|
|
|
What are producers?
|
Producers are organisms that use the sun to make their own food. Most producers use chlorophyll during photosynthesis.
|
|
|
What are some examples of producers?
|
Eubacteria--cyanobacteria
Protista--algae and other plant-like protists Plantae--all plants |
|
|
What are consumers?
|
Consumers are organisms that cannot make their own food from the sun.
|
|
|
What are some examples of consumers from different kingdoms?
|
Animals, fungus, Eubacteria, animal-like and fungus-like protists
|
|
|
What are decomposers?
|
A decomposer is a type of consumer. Bacteria, fungi and others consume waste and dead organisms, helping to recycle nutrients
|
|
|
What are some examples of decomposers from different kingdoms?
|
Eubacteria--many kinds
Fungi--mushrooms, molds, mildews Protists--fungus-like |
|
|
What is a food web?
|
A food web shows all the possible feeding relationships within a community.
|
|
|
What is the energy pyramid?
|
Shows the amount of energy available at each feeding level in an ecosystem.
|
|
|
What level makes up the upper level?
|
As you move up the pyramid, each level becomes smaller. Only 10% of the energy from each level is passedf to the next. Consumers make up the upper levels.
|
|
|
What is ecology?
|
The study of the interactions that take place between organisms and their environment.
