Module D Chapter 3

Sections 3-1 & 3-2

Grade 5


Plants l.jpg
Plants

  • Water usually enters plants through the roots

  • Water vapor & oxygen exit the leaf


Photosynthesis l.jpg
Photosynthesis

  • Plants trap light energy and use it to make sugars

  • This process is called photosynthesis


First stage of photosynthesis l.jpg
First Stage ofPhotosynthesis

  • Chlorophyll absorbs sunlight

  • Light energy is changed to chemical energy

  • Water breaks down into hydrogen & oxygen

chlorophyll


Second stage of photosynthesis l.jpg
Second Stage of Photosynthesis

  • In sunlight, green leaves use carbon dioxide and water to make sugars, and oxygen is released


Chlorophyll l.jpg
Chlorophyll

  • The substance in green plants that gives it color and absorbs light is chlorophyll


Chloroplasts l.jpg
Chloroplasts

  • Photosynthesis takes place in the chloroplasts


Respiration l.jpg
Respiration

  • Process in which sugar reacts with oxygen to make carbon dioxide & water in plants

  • Plants use oxygen to break down sugar molecules to release useful energy


Producers l.jpg
Producers

  • Organisms that make their own food

  • Examples: Algae & Plants

  • They give off oxygen


Consumers l.jpg
Consumers

  • Organisms

  • Get energy from stored chemical energy in food they eat

  • They give off carbon dioxide


Herbivore l.jpg
Herbivore

  • A consumer that eats only producers

  • Example: elk

  • consumer

  • producer


Carnivore l.jpg
Carnivore

  • Consumer that eats only other consumers

carnivore


Omnivore l.jpg
Omnivore

  • A consumer that eats both producers and consumers


Decomposers l.jpg
Decomposers

  • Bacteria & fungi that break down dead organisms are called decomposers


Food web l.jpg
Food Web

  • System of chains in an ecosystem


Food chain l.jpg
Food Chain

  • Simple feeding pattern

  • Shows transfer of energy from 1 organism to another

  • Energy is lost at each step
