Energy
Us humans and other organisms need to eat food for energy, but organisms with a chloroplast can just do this instead.
What is photosynthesis?
A food chain shows how ________ is passed from one living thing to another.
What is energy?
The main gas, known as a greenhouse gas, that is responsible for global warming and climate change.
What is carbon dioxide?
The process by which a species ceases to exist due to factors like habitat loss, overhunting, and climate change is called this.
What is extinction?
These imaginary lines between molecules and elements are broken and recreated in order to digest (break down) and synthesize (create) new materials.
What are bonds?
A food chain ALWAYS begins with __________
What is a producer?
This human activity has significantly increased the amount of carbon dioxide in the atmosphere over the last 200 years with the development of factories and increased urbanization.
What is the burning of fossil fuels?
The increase in global temperatures and changes in weather patterns, resulting from human activities poses a threat to biodiversity by causing this.
What is climate change?
The main source of energy in an ecosystem comes from here
What is the sun?
Plants need these 3 inputs (reactants), so that they can create energy for themselves!
What is water, carbon dioxide, and sunlight?
A food ____ is more complex than a food chain because it includes more organisms and their interactions.
What is a food web?
Deforestation greatly _________ the amount of carbon dioxide in the atmosphere, contributing to rising global temperatures and climate change.
What is increases?
The clearing of forests to create agricultural land or urban areas is an example of this human activity, which is a major threat to biodiversity.
What is deforestation/habitat destruction?
As you move up this triangular structure, the amount of energy transferred decreases.
What is an energy pyramid?
This macromolecule can be consumed, but amino acids are also made in our bodies from our DNA.
What are proteins?
Label each trophic level in the food chain shown here
Carrots > Rabbit > Fox > Lion
What is producer, primary consumer, secondary consumer, tertiary consumer (or apex predator)?
This "sphere" on earth is where all living things reside, and carbon is constantly being cycled through here.
What is the biosphere?
A _________ ecosystem is one that is resilient to change. Biodiversity helps to increase this resiliance.
What is stable?
In the food chain:
grass > rabbits > snakes > owls
______ has the highest amount of energy available.
What is grass?
This carbohydrate is consumed by animals and used for energy during cellular respiration, but plants are able to make it themselves.
What is glucose?
In the food chain:
grass > rabbits > snakes > owls
If the population of snakes were to increase, the population of grass would eventually ________
What is increase?
During respiration, carbon is cycled from the biosphere to the ____-sphere as it is released by organisms.
What is the atmosphere?
