sacs that are found in chloroplasts
thylakoids
100
the overgrowth of algae
algal bloom
100
attraction between the hydrogen of one molecule and the oxygen of a nearby molecule
hydrogen bond
100
three different (models) of ecological pyramids

Herbivores are organisms that eat plants. Therefore they are called
primary consumers
200
process in which carbon dioxide is attached to RUBP molecules
carbon fixation

producers can only use phosphorus if it is in the form of _____
phosphate

molecule with an uneven distribution of charge (water is a _____ molecule)
polar molecule

model of food (energy) transfer in an ecosystem that shows the connections among food chains.
food web
300
layer of cells that contain the chloroplasts
mesophyll
300
converting nitrogen gas into ammonium N2->NH4
nitrogen fixation

Explain "rule of 10"
10% of the energy at one trophic level is transferred to the next trophic level
400
a feeding level through which energy and matter are transferred; indicates an organism's position in the food chain and is determined by the number of energy transfer steps required to reach each level
trophic level
400
____ synthesize ATP from ADP molecules
enzymes
400
process by which sulfur and nitrogen emissions undergo chemical change in the atmosphere and are deposited in the environment as dry particles and gases, or as ______
acid deposition
400
The water that is produced by cellular respiration is?
metabolic water
400

Explain the role of decomposers in a food chain
They obtain energy-rich molecules by eating or absorbing leftover or waste matter. They return organic and inorganic matter to the soil, air, and water. These materials can then be used again by producers to make new energy- rich organic molecules.

500
the attraction of water molecules to each other
cohesion
