Bio ch 4 ecosystem ecology Flashcards
What is the summative chemical equation for photosynthesis?
6CO2 + 6H20 + (light) → C6H12O6 + 6O2
Explain why an individual plant would undertake photosynthesis (what’s the point for the plant)
Photosynthesis is important to plants because it allows them to make glucose, which is needed to make energy and cellular structures.
Write the summative chemical equations for glycolysis + cellular respiration by themselves
C6H12O6 —> 2C3H6O3 +2 ATP
Write the summative chemical equations for glycolysis + cellular respiration together.
C6H2O6+6O2 —> 6CO2+ 6H2O+36ATP
Explain why an individual plant would undertake glycolysis + cellular respiration (what’s the point for the plant).
Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP. This process releases carbon dioxide and water as waste products.
Explain how the carbon cycle is relevant to global climate change.
The burning of fossil fuels, rapidly releases carbon dioxide (CO2), a greenhouse gas into the atmosphere, increasing average global temperatures and causing ocean acidification.
what a biome is
geographical region classified according to the main plant types present that determine factors of temp and precipitation.
Which two abiotic factors are the main determinants of biome type?
temp and precipitation.
Explain what the greenhouse effect is and how it is connected to climate change
the way in which heat is trapped close to Earth’s surface by “greenhouse gases.” These heat-trapping gases can be thought of as a blanket wrapped around Earth, keeping the planet toastier than it would be without them
What is a population
group of individuals of the same species in a single area
What is a community
an interacting group of various species in a common location
What is an ecosystem?
geographic area where plants, animals, and other organisms, as well as weather and landscapes
