Cell Resp. & Photosynthesis
What are the reactants for photosynthesis?
CO2 and H2O
The maximum number of organisms an ecosystem can support without damaging the ecosystem is the __________ _________ . This is represented by the population curve leveling off.
Carrying Capacity
________ is the hereditary material found in all living things passed from parent to offspring.
DNA
The movement of molecules form a high to low concentration. No energy is required.
diffusion (passive transport)
Give an example of a biotic factor
Any living factor
What are the products of photosynthesis?
O2 and Glucose (C6H12O6)
According to the 10% rule, if a plant produces 6,000 kg of energy and is eaten by a field mouse (primary consumer), the mouse only receives ______ kg of energy
600 kg
Maintaining a stable internal environment is which characteristic of life? (EX: blood sugar, body temp)
Homeostasis
This protein in the membrane creates an opening and allows large molecules to enter and exit the cell.
Channel Protein
In an ecosystem, energy FLOWS while matter _________
Cycles
What are the reactants for cellular respiration?
O2 and Glucose (C6H12O6)
When populations grow continuously and quickly before reaching carrying capacity, or may have gone passed carrying capacity.
Exponential Growth (J-curve)
All living things are made up of _________
cells
This macro molecule is in the form of fats and oils and makes up our cell membranes.
Lipid
This is a symbiotic relationship where one species benefit and the other is unaffected.
commercialism
What are the products for cellular respiration?
CO2, H2O, and ATP energy
__________ is an organisms functional role in the community.
Niche
Living things get and use energy. This process is called......
Metabolism
This protein in the cell membrane receives and sends signals to and from other cells.
Receptor Protein
Humans have bacteria in their gut that helps us digest food and the bacteria also revive nutrients in return.
Mutualism
Cellular respiration happens in the _________ of all living organisms, while photosynthesis occurs in the ____________ of plant cells only.
mitochondria, chloroplast
Organisms that if removed from the ecosystem will have drastic/damaging impacts on the ecosystem and other organisms are called ________ ________ (EX: wolves of Yellowstone)
Keystone Species
What are the three components of the life cycle?
Growth, Reproduction and Death
The movement of large molecules from low to high concentration across a membrane. Also requires ATP energy.
active transport
Carbon, Oxygen, Hydrogen, Nitrogen, Phosphorus, sulfur.
