Cycles
What is the purpose of the water cycle?
It recycles water
What is a food chain?
What is a food web?
Food Chains are pictorials that show the flow of energy. They show one path, one food option.
What do plants need to grow?
Gases (oxygen and co2) and water and sunlight
Define decomposers?
Organisms that breakdown and recycle energy within an ecosystem
What is the difference between evaporation and transpiration?
Transpiration involved plants and is liquid to gas
What is the difference between food webs and food chains?
Food Chains only show ONE food choice, one pathway for energy flow.
What is the difference between photosynthesis and respiration
Photosynthesis- during the day, makes food, uses sunlight and CO2
Respiration- happens at night, uses a bit of energy to grow, reproduce and repair.
Explain the role of the sun in the water cycle
The sun drives the water cycle by facilitating evaporation
Why would rain water run-off instead of percolate/infiltration?
Run off might happen if the water falls on an incline or if the soil is hard and compact
Which part of a food chain or food web does NOT need decomposers?
Decomposers are organisms that breakdown and recycle energy. EVERY part of a chain or web needs decomposers since organisms, at all levels, die and must be broken down and its energy recycled.
Which element is responsible for "where all that matter came from?" Explain
Carbon
What is hydroponics?
Growth of plants in water without soil
Name the steps of the water cycle
Evaporation & transpiration, condensation, precipitation, run-off, infiltration, & groundwater
Talk about the arrows of a food chain or web.
Arrow points to the predator
Arrows show direction of the flow of energy
Explain the Law of Conservation of Matter related to the window experiment
The matter came from the sugar made during photosynthesis being captured in the bonds of carbon
When would "competition" become an issue in an ecosystem.
Competition is natural in an ecosystem.
Competition results in an ecosystem when the prey/predator relationship is off balance.
Which step of the water cycle could be eliminated and why?
None
Explain CARRYING CAPACITY
Earth's ability to give its organisms EVERYTHING they need.
Food, water, shelter and space.
What is the name of a plant's reproductive process
Pollination
Tell me everything you know about carbon
Found in all living things
Responsible for fossil fuels
Atomic number is 6
