heterotroph

all animals and fungi and many single-celled organisms

ATP

All organisms burn glucose to form ____________ during cellular respiration.

(a)Autotroph, (b)Heterotroph, (c)Autotroph, (d)Heterotroph, (e)Heterotroph

Determine if the following are autotrophs or heterotrophs: (a) a giant redwood tree, (b) a spider, (c) a rose bush, (d) a mushroom, € a blue whale.

Autotrophs are organisms that make their own food. Heterotrophs are living things that cannot make their own food.

Distinguish between autotrophs and heterotrophs.

Oxygen

Glucose and ____________ are the products of photosynthesis.

Food

Heterotrophs are living things that cannot make their own ____________.

Energy is required to break down and build up molecules and to transport molecules across plasma membranes. All life's work needs energy. A lot of energy is also simply lost to the environment as heat.

How is energy used in a cell?

a. the grass b. the grass and grasshopper c. the hawk d.the grasshopper, snake, and hawk

In the food chain grass → grasshopper → snake → hawk, which organism(s) are the heterotrophs?

Energy

Living organisms get their ____________ from food.

a. uses the energy in sunlight to make food. b. uses the glucose in sunlight to make food. c. uses the energy in sunlight to make ATP. d. breaks down glucose to form ATP.

Photosynthesis

a. uses carbon dioxide and water, in the presence of sunlight, to produce food (glucose) and oxygen. b. uses glucose and oxygen to produce energy for the cell (ATP), releasing carbon dioxide and water. c. uses glucose and oxygen, in the presence of sunlight, to make ATP. d. uses carbon dioxide and water, in the presence of sunlight, to produce ATP and oxygen.

Photosynthesis can be described as the process that

Light

Photosynthesis is the process in which energy from ____________ is transferred to glucose.

Chloroplasts, Heterotrophs

Photosynthesis occurs in the ____________, and cellular respiration occurs in the ____________.

C6H12O6

The chemical formula of glucose is ____________.

a. 6CO2 + 6O2 → C6H12O6 + 6H2O. b. 6CO2 + 6H2O → C6H12O6 + 6O2. c. C6H12O6 + 6O2 → 6CO2 + 6H2O d. C6H12O6 + 6CO2 → 6O2 + 6H2O

The correct chemical formula for photosynthesis (in the presence of sunlight) is

cellular respiration

The process in which glucose is broken down and ATP is made

Energy - the ability to do work. A bird flies through the air, a firefly glows in the dark, a dog wags its tail

What is energy? Give an example of how energy is used in a living organism.

a. a maple tree b. the blue-green bacteria known as cyanobacteria c. Laurencia, a marine genus of Red Algae from Hawaii. d. All of the above are producers.

Which of the following autotrophs is also a producer?

a. statement 1 only b. statements 2 and 3 only c. statements 1, 2, and 3 only d. All 4 statements are correct.

Which of the following statements is true about glucose and ATP? (1) Glucose is made during photosynthesis. (2) The energy in sunlight is temporarily stored in glucose before it is transferred to ATP. (3) ATP is the energy-carrying molecule that cells use for energy. (4) The processes that make ATP and glucose also recycle oxygen in Earth's atmosphere.

a. The products of photosynthesis are the reactants of cellular respiration. b. The products of cellular respiration are the reactants of photosynthesis. c. Both statements are true. d. Neither statement is true.

Which of the following statements is true?

a. A lion eating an antelope. b. A caterpillar eating a leaf. c. A snake eating a rat. d. A flower absorbing sunlight.

Which statement best describes the relationship between a consumer and a producer?

Autotrophs are also called producers. They produce food not only for themselves but for all other living things as well. This is why autotrophs form the basis of food chains.

Why are autotrophs considered the basis of food chains?

Oxygen

Without photosynthesis, there would be no ____________ in the atmosphere.

Glucose, ATP

____________ and ____________ are the two types of molecules organisms use for chemical energy.

Cellular Respiration

____________ is the process in which energy from glucose is transferred to ATP.

Autotrophs, Heterotrophs

____________ make their own food, whereas ____________ get food by eating other living things.

Carbon Dioxide

____________, water, and energy are the products of cellular respiration.

glucose

stores chemical energy in a concentrated, stable form

producer

also known as autotrophs

food

organic molecules that store energy in their chemical bonds

decomposer

organism at the end of a food chain

autotroph

organisms that make their own food

consumer

organisms that must eat

photosynthesis

process that stores energy from sunlight in the chemical bonds of glucose

food chain

shows how energy and matter flow from producers to consumers

energy

the ability to do work

ATP

the energy-carrying molecule that cells use for energy
