Name three important needs for water.
Drinking, Washing, Cleaning.
Cellular Respiration, Digestion, Photosythesis.
Photosynthesis, Digestion, Human Use
What are macronutrients?
Nutrients used in big amounts.
Nutrients used in small amounts.
Big puzzle pieces.
What percent of the air is nitrogen?
70%
78%
94%
Why is phosphorous an important biological molecule ?
It takes part in food, cells, and plants.
It takes part in photosynthesis, and it is used in the cell membrane.
It takes part in photosynthesis, nucleic acids, and phospholipids.
How is water distributed through the biosphere?
Rain and evaporation.
Precipitation and evaporation.
Snow and evaporation.
What are micronutrients?
Nutrients used in large amounts.
Why is nitrogen essential to life?
It's necessary for us to breathe.
It's a part of amino and nucleic acids.
It's part of nucleic acids and cell membrane.
What happens to phosphorous that erodes from rock and soil?
It dissolves and washes into rivers and streets.
It stays in the rock until it slowly dissolves in a process of five years.
It never dissolves.
Gravity draws water back to Earth.
Transpiration is sweat.
The soil in the ground determines what plants grow where.
An aquifer is an permeable rock site where water can pass through easily and the water below this is also called groundwater.
Seepage from Ground and Runoff from surface are two ways water travels from land to ocean.
Runoff only includes flows from rivers and/or streams.
80% of water enters the hydrologic cycle.
55% of water fall back as rain in the hydrologic cycle.
Most of the carbon located on Earth is in the atmosphere as carbon dioxide.
Carbon enters the biotic parts of the ecosystem through water.
The function of plants in the forest is to take carbon dioxide and turn it into oxygen.
Carbon dioxide is returned to the atmosphere when any living thing exhales.
A primary producer is a living thing that can make food on its own.
When primary and secondary consumers die the carbon stays in their bodies.
Detritus feeders don't contribute in anything at all in the carbon cycle.
Fossil fuels are oils, gasses, and coal.
Carbon gets in the ocean because it's in the atmosphere and seashells also release it.
Plants and animals get nitrogen from nitrogen fixation if they can't get it from the atmosphere.
Nitrogen fixing bacteria turn the nitrogen into nitrogen gas.
Air is a major reservoir for ammonia.
Herbivores need nitrogen because they eat plants and plants need nitrogen.
Dentrification is the process in which carbon is converted into energy.
There's no phosphorous in plants or animals.
Phosphates return to the ecosystem and/or plants when an animal or a plant dies.
Phosphorous carried by runoff to the oceans gets concentrated in: marine rocks, fish's body, sea plants.
Phosphates are incorporated into aquatic plants and animals by water.
The difference between the phosphorous cycle and the water, carbon and nitrogen cycle is in phosphorous's cycle phosphates never return to the atmosphere.
