Which of the following organisms is best described
Which of the following organisms is best described as an autotroph? (1) (3) Het erot roph s! (2) (4)
Make food from sunlight and raw materials Eat other things
Notice that the matter (molecules) cycle around.
Where does the energy ORIGINATE?
Cells have organelles that store & release energy. Chloroplast & Mitochondrion s i e n o h c i Y h L W N O d n fou nt cells? a l p in Whi ch is foun in BO d T H plan & an t imal cells ?
Chloroplasts “catch” light energy, and store it in the chemical bonds of sugars. Actual chloroplast micrograph Oxygen Phot osyn thesi s t h g i L Glucose Where are chloroplasts found? Carbon Dioxide + Water
Chloroplasts are organelles found in the leaf cells of plants. Glucose Light energy is stored here!
Mitochondria are organelles that release the energy stored in glucose. Actual mitochondrion micrograph Glucose + Oxygen n o i t a r i Resp Carbon Dioxide + Water ATP Where are mitochondria found?
The cycle in nature looks like this! Glucose & Oxygen Actual mitochondrion micrograph t Carbon Dioxide + Water Ligh ATP Actual chloroplast micrograph
ENERGY is on a “one way” trip. What happens to Matter CYCLES life on Earth if through the SUN stops environment. shining? Life would run out of ENERGY!
The flow of energy in an ecosystem is best described as energy moving in (1) one direction from the Sun to the autotrophs and then the heterotrophs (2) one direction from a consumer to a producer and then to the Sun as heat and light (3) two directions between the producers that are present (4) two directions, back and forth, between the producers and the consumers
