Photosynthesis 1
In this process, light energy from the sun is used to transform water and carbon dioxide into sugar and oxygen.
What is photosynthesis?
The carbon in the products of photosynthesis comes from this light-weight molecule.
What is carbon dioxide?
This part of a chemical equation is placed to the left of the yield arrow.
What are the reactants?
This part of a chemical equation is placed to the right of the yield arrow.
What are the products?
The products of photosynthesis can be used for these four energy-requiring processes.
What are growth, development, metabolism, and reproduction?
Organisms like kelp, phytoplankton, and plants that perform photosynthesis are in this trophic level.
What are producers?
The glucose produced by photosynthesis can be converted into other biological molecules. Identify at least TWO.
What are other sugars, cellulose, starch, lipids, phospholipids, steroids, waxes, proteins, and nucleic acids?
Energy can be transferred when biological molecules are broken apart and these are rearranged.
What are (chemical) bonds?
Photosynthesis does not provide all of the necessary biological molecules; photosynthetic organisms require this additional element to produce amino acids.
What is nitrogen?
Products of photosynthesis
What are glucose and oxygen?
As free oxygen started to build in the atmosphere, the size and diversity of organisms in the biosphere changed in this way.
What is an increase?
The word equation for photosynthesis.
carbon dioxide + water + light energy yields glucose + oxygen
Atmospheric nitrogen is unusable by most living things; instead, it must be converted into usable nitrates by these type of organisms
What are (soil) bacteria?
When consumers eat their food, they break the chemical bonds of the proteins in their food, and rearrange these building blocks to make their own proteins.
What are amino acids?
When water is split using the energy from sunlight, this waste product of photosynthesis is produced.
What is oxygen?
The products of photosynthesis have more stored energy than the reactants of photosynthesis, requiring an input of energy from this source
What is the sun?
This sphere changed significantly once plants evolved root systems
What is the geosphere?
In the first step of photosynthesis, light energy excites chlorophyll, causing this reactant molecule to be split.
What is water?
Atmospheric nitrogen can be converted to soil nitrates by specialized bacteria and this other process
What is lightning?
Since photosynthetic organisms cannot produce all of the biologically important molecules they need, this cycle is necessary for them to obtain an important element
What is the nitrogen cycle?
Chemical energy is this type of energy
What is stored energy?
Reason why oxygenation of the atmosphere led to greater size and diversity of species
What is more cellular respiration releasing more energy leading to more growth, development, metabolism, and reproduction?
When light energy excites this molecule, water molecules are split and the energy released is used to power the conversion of carbon dioxide into glucose.
What is chlorophyll?
The chemical equation for photosynthesis
What is 6 CO2 + 6 H2O + light energy yields C6H12O6 + 6 O2?
In photosynthesis, light energy is converted into chemical energy. When consumers eat their food, this type of energy is converted into chemical energy
What is chemical energy?
