Energy Flow In Biosphere Flashcards
What order of trophic levels? Starting from the bottom
Decomposers (detritivores), tertiary consumers, secondary consumers, primary consumer (heterotrophs), producer (autotrophs)
What is the difference between food chains and food webs?
.
Who does energy transfer lost between trophic levels?
.
What is the 10% rule of food chains?
When a predator eats its prey, the predator only gain 10% of the preys energy.
Define carbon sink
The natures (ocean, forests, etc.) ability to absorb carbon dioxide from the atmosphere
Define herbivore
An animal that eats only plants
Define carnivore
An animal that feeds only on other animals
Define omnivore
An animal that eats both plants and other animals
Define biomass
The total dry mass of all the living material in a ecosystem
How does the greenhouse effect and greenhouse gases apply to climate change?
CO2, CH4, NOx
How does the albedo effect apply to climate change?
Cryoconite found on glaciers
What is bioaccumulation in a ecosystem?
Substances (pesticides, chemicals, etc.) that the organisms absorb at a rate faster than which substance is lost
What is the flow of water (water cycle) throughout the planet?
.
How have human influences had a disruptive impact on the balance between photosynthesis and cellular respiration or oxygen and carbon dioxide?
.
What is the process were scientists are able to drill into glaciers and take ice core samples as means to determine historic levels of atmospheric CO2?
They drill the glaciers to find air bubbles to measure the CO2
