Organize your life
All the relationships between the living and non-living things in a community
ecosystem
All the organisms in an ecosystem
community
This gas found in air allows you to release and use energy from food.
oxygen
These are plants. They make their own food using energy from the sun
producers
These only eat plants
herbivores
When a lion eats a zebra, the zebra is known as the:
prey
Non-living things in an ecosystem
abiotic
A collection of related ecosystems
biome
Your cells are made up of 70% of this. This is where chemical reactions take place.
water
The process that producers use to make their own food
photosynthesis
These eat mostly meat
carnivores
Snails and earthworms are examples of these. They feed off waste.
detritivores
Living things in an ecosystem
biotic
The Earth and all the ecosystems within it
biosphere
Living things need this for energy, growth, movement, repair, making more cells
food/nutrients
What are three roles that producers play in an ecosystem?
produce oxygen, supply food, shelter
These eat both plants and meat
omnivores
Fungi and bacteria are examples of these. They break down dead organic matter
decomposers
A single living thing
organism
True or False?
The "organization of life" can be described as follows:
An organism belongs to a population. A population belongs to a community. A community belongs to an ecosystem. An ecosystem belongs to a biome. A biome belongs to the biosphere.
True
All the things needed for survival, including shelter
habitat
If this layer of a food chain disappeared, the entire ecosystem would collapse.
producers
When a lion eats a zebra, the lion is known as the:
predator
At each level of a food chain, what three things do consumers do with the energy found in the food?
bodily functions, heat, stored
Population
True or False?
Light, rain, and air are biotic factors in the environment.
false
The fancy name for how cells convert energy in sugars to a form that they can use
cellular respiration
What gas plays a role in climate change? What layer of the food chain can help to control this gas?
carbon dioxide, producers
These are consumers that feed off dead animals
scavengers
What percentage of energy taken in by a food source is available to the organism that consumes it?
10%
