Energy Flow in Ecosystems
What is the relationship between a food chain and a food web?
A food web is made of many interconnecting food chains
This part of the ocean is barely reached by sunlight
The deep zone (of the open ocean)
Which biome contains mostly grasses and shrubs and gets a medium amount of rain?
Grassland
Biotic factor
Something in an environment that is alive or once was alive
What is it called when water vapor collects into tiny droplets of liquid?
Condensation
What are some adaptations an animal might have to allow it to avoid predation?
Camouflage, long legs to run fast, being small to hide, good sense of smell to detect predators, etc.
Organisms in this area of the ocean must be adapted to rough waves and changes in tides
Intertidal zone
Deciduous forest
Climate
General description of an area's temperature and amount of precipitation
True or False: Free nitrogen can be used by plants to grow
False
First level consumer
Name three abiotic factors affecting aquatic ecosystems
Temperature, sunlight, depth, pressure, salt, etc.
What determines what biome an area will be?
Its climate (precipitation and temperature)
Producer
An organism that makes its own food, usually from the sun's energy
What is the role of plants in the oxygen cycle?
To produce oxygen through photosynthesis
Where does all of the energy in an ecosystem come from originally?
The sun
The place where a freshwater ecosystem meets a saltwater ecosystem is called this
Estuary
Why are rainforests able to support so many different species of animals?
Rainforests have lots of rain and are very warm, which allows tons of plants to grow to provide food and shelter for animals
Consumer
An organism that must eat other things to get energy
What are the main roles of animals in the carbon cycle?
Breathing out carbon dioxide and consuming carbon from plant matter
In an energy pyramid where the base producer level has 20,000 calories of energy, how much energy will the 2nd level consumers have?
200 calories
This part of the ocean does not change with the tide and has many different animals and photosynthetic algae
Neritic zone
Describe one way a plant could be adapted to a desert
Legume
a type of plant whose roots tend to shelter nitrogen-fixing bacteria
In the nitrogen cycle, how does free nitrogen become fixed nitrogen?
Bacteria found around the roots of legumes convert it
