3.1
What is the combined portions of Earth where all life exists called?
the biosphere
What is the difference between weather and climate?
Weather is day-to-day conditions; climate is long-term patterns.
A group of ecosystems with similar climates and organisms is called a
biome
What is the main source of energy for most life on Earth?
the sun
A sequence showing energy transfer by eating and being eaten.
food chain
Which level of ecological organization includes all the organisms that live in a place, together, with their non-living environment?
an ecosystem
What causes different parts of Earth to have different climates?
Uneven heating of Earth’s surface due to its tilted axis
dense covering formed by the leafy tops of tall rainforest trees
canopy
What type of organism makes its own food using sunlight or chemicals?
autotroph
plants releasing water vapor from their roots/ leaves into the atmosphere is called
transpiration
Listing both...
Give one example of a biotic factor and one abiotic factor in an ecosystem.
Biotic = living something (dogs / people / trees / etc.)
Abiotic = non-living something (wind / water / rock / temperature / sunlight)
Trapping of heat that keeps the earth warm is called
the greenhouse effect
what's the difference between the photic zone and the aphotic zone?
sunlight
Ecological pyramids are models that show the relative amount of ______________ contained within each trophic level in a food chain or food web
energy / matter
nitrogen gas -> nitrogen compounds/nitrates is the process of ________________
while nitrogen compounds/nitrates -> nitrogen gas is ________________
nitrogen fixation, denitrification
List the 4 spheres of ecology and one thing they each include
hydrosphere - water
geosphere - rocks
atmosphere - gases
biosphere - animals
If there was no greenhouse effect, the earth would be
colder
which two factors determine a biome's climate?
temperature and precipitation
How do decomposers and detritivores differ in their role?
Decomposers produce; detritivores consume/ feed
what do we call processes that recycle elements like water, carbon, nitrogen, and phosphorus through ecosystems.
biogeochemical cycles
what is the correct order of ecological organization? (hint: there's 6 levels)
species -> population -> community -> ecosystem -> biome -> biosphere
