Cells: energy

Question 1

How do autotrophs aquire energy?

Answer 1

use photosynthesis to convert sunlight, carbon dioxide, and water into glucose (type of sugar) and oxygen

Question 2

How do heterotrophs aquire energy?

Answer 2

cannot produce their own food and instead obtain energy by consuming other organisms or organic matter

Question 3

What are chemical bonds?

Answer 3

Attractive forces that act as glue and hold/link atoms together in molecules or compounds. These bonds are formed when atoms share electrons or transfer them. If the chemical bonds were to be broken, chemical energy would be released

Question 4

What are the 3 main types of chemical bonds?

Answer 4

1. Ionic bonds - form when a atom transfers electrons to another atom. creates ions with opposite charges
2. Covalent bonds - when atoms share electrons to get a stable electron configuration
3. Hydrogen bonds - forms between a hydrogen atom bonded to a electronegative atom and another nearby electronegative atom

Question 5

What are energy consumers?

Answer 5

Energy consumers (heterotrophs) are organisms that can’t make their own food and rely on other organisms for energy

Question 6

What are energy consumers?

Answer 6

Energy consumers (heterotrophs) are organisms that can’t make their own food and rely on other organisms for energy
