Unit 1 all vocab (will soon be added to unit 1 review deck) Flashcards
(20 cards)
Water cycle steps
infiltration
Water seeps into the soil and becomes groundwater
Water cycle steps
transpiration
Water is taken up by plants and evaporates into the atmosphere
Primary productivity
the rate at which producers, such as plants, convert sunlight into organic matter
Primary productivity equation
NPP=GPP-RL(respiration Loss)
New Primary Productivity (NPP)
the amount of energy stored by plants after cellular respiration
Gross primary productivity (GPP)
the total amount of energy produced by plants
Respiration Loss (RL)
the energy lost by plants due to cellular respiration
Trophic Pyramid
A trophic pyramid is a way to represent the flow of energy through an ecosystem, The pyramid is shaped because each level only receives 10% of the energy from the level below
Producers
plants convert sunlight into organic matter
primary consumers
herbivores eat plants and get energy
secondary consumers
carnivores eat primary consumers and get energy
tertiary consumers
apex predators eat secondary consumers and get energy
Energy flow through trophic levels
producers
100%
Energy flow through trophic levels
primary consumers
10%
Energy flow through trophic levels
secondary consumers
1%
Energy flow through trophic levels
tertiary consumers
0.1%
Movement of energy and matter
In a food web or food chain, arrows represent the movement of energy and matter from one organism to another
trophic Cascade
Powerful effects of predators in an ecosystem, where the removal of one species can have a significant impact on the organisms in the rest of the food web
Importance of top predators
Top predators like wolves and hawks, often control herbivore population in their ecosystem which can result in an increase at the producer level
Phosphorus reservoirs
soil
Phosphorus is released from rocks and sediments through weathering and erosion and is stored in soil
