Ecosystems 1
Many of the same species is a...
What is a population?
Plants source of energy
What is sun
what powers cellular respiration
At the bottom of the food pyramid, what are those organisms called
What are producers
organism that feeds on plant and animal remains and other dead matter
What is a detritivore?
Plants use this process to turn light into chemical energy
What is photosynthesis?
What types of organisms do some form of respiration
ALL: plants, animals, humans, bacteria, etc.
An organism that uses sunlight to create its food
What is a producer
Living organisms in an ecosystem are called...
What is biotic?
Equation for photosynthesis in words
-label reactants and products
carbon dioxide + light + water --> Oxygen + glucose
Cellular respiration in words
Glucose + Oxygen --> carbon dioxide + water + ATP
Food chains that is interconnected/overlaps in a particular ecosystem
What is a food web?
Air, water, and the Sun are all ......
What is are abiotic factors?
What is carrying capacity?
Are carrying capacities the same for all populations?
Can carrying capacity change for a population?
-Maximum number of individuals of a species that an area can hold
-no
-yes
2 reasons photosynthesis important for ecosystems
1. creates oxygen, which organisms need for cellular respiration
2. Creates energy for other organisms
How are cellular respiration and photosynthesis related to each other
photosynth makes oxygen and glucose which are used in cellular respiration
cellular resp. makes carbon dioxide and water which are used in photosynth
Create a food web with at least 7 animals
answer
bacteria, fungi, worms, ants, beetles, sow bugs
What are some examples of decomposers?
List how each type of matter is important (nitrogen, oxygen, carbon, and water)
Nitrogen: DNA and protein
Oxygen: Used in cellular respiration
Carbon: Energy and molecules in your body
Water: All organisms need
Photosynthesis equation in chemical formulas
CO2 + H2O + light --> C6H12O6 + O2
How are photosynthesis and cellular respiration important for the cycles of matter.
photosynth. supplies oxygen to the oxygen cycle. and carbon to the carbon cycle
cellular respi. supplies water to the water cycle, and carbon to the carbon cycle
Create an energy pyramid with 3-4 levels. Put organisms and amount of energy in each level
