Photosynthesis
The process that ecosystems use to convert sunlight into energy
photosynthesis
The process of cellular respiration occurs in _______________________________.
Both plants and animals
What happens to most of the light energy during photosynthesis?
It is transformed into chemical energy
Which step in the carbon cycle involves the transformation of carbon dioxide into oxygen?
photosynthesis
The pathway of carbon through the carbon cycle is:
_______ > plants >________> ground
atmosphere, animals
What are the 2 products of photosynthesis?
Sugar and oxygen
This is what animals do with the carbon dioxide produced in their cells during cellular respiration.
Exhale it in the breathing process
What activity allows organisms to get the energy they need to grow, breathe, and move?
consume other organisms (eat)
Describe the roles of photosynthesis and cellular respiration in the carbon cycle.
Cellular respiration adds carbon to the atmosphere, photosynthesis removes it.
A ___________ amount of carbon exists on earth, and it moves through _______ & _________ materials through the _________ cycle.
finite, living, non-living, carbon
Describe the process of photosynthesis in words.
Carbon dioxide and water are turned into glucose(sugar) and oxygen
the organelle where cellular respiration takes place
mitochondria
How does photosynthesis follow the Law of Conservation of Energy
Light energy from the sun is converted into chemical energy in plant cells.
What happens to the carbon stored in leaves when they decay?
The carbon is converted into carbon dioxide and released into the atmosphere
Why do bubbles form when you put a plant leaf into a glass of water?
photosynthesis is occurring, oxygen gas causes the bubbles to form
This pigment absorbs energy from sunlight and converts it into stored energy in food.
Chlorophyll
what is the equation for cellular respiration in words
glucose + oxygen --> carbon dioxide + water + energy
what is the energy source for cellular respiration?
glucose
If you performed an experiment in a closed jar, measuring the amount of carbon at different stages of the carbon cycle, the amount of carbon would ______________.
remain constant throughout the experiment
What part of this statement is incorrect? and why?
Plants take in carbon dioxide, an animal then consumes the carbon dioxide and uses it as energy, then exhales, returning carbon to the atmosphere.
"animal then consumes the carbon dioxide and uses it as energy"
animals don't use carbon dioxide as energy, they use carbohydrates.
Where in the plant do the reactants for photosynthesis enter?
carbon dioxide through the leaves, water at the roots, and light energy by chlorophyll in plant cells.
ATP
Adenosine Triphosphate
How do plants & animals get the energy they need?
Plants break down glucose they produced during photosynthesis and animals get energy from eating other organisms
How do herbivores contribute to the carbon cycle?
how can students improve the validity of their research on ecosystems?
using multiple reputable sources
