Do now l.jpg
DO NOW

  • 1. Which biome is cold, has flat, bare land, few plants and animals, and permafrost?

  • 2. What makes up a community?

  • 3. What makes up a population?


Slide3 l.jpg
GOAL

  • To understand energy flow through food chains, food webs, and energy pyramids


Food chains l.jpg

Energy

1. Produced by sun

2. Needed by all living things

3. Animals obtain energy by eating plants

Food Chains


Food chains5 l.jpg

Food Chain

Energy passed between living things through food

Food Chains


Food chains6 l.jpg

Food Web

Several overlapping food chains

Food Chains


Food chain members l.jpg

Predator

An animal that eats other animals for food - “hunter”

Food Chain Members


Food chain members8 l.jpg

Prey

An animal eaten by a predator

Food Chain Members


Food chain members9 l.jpg

Herbivore

Animals that eat only plants

Food Chain Members


Food chain members10 l.jpg

Carnivore

Animals that eat other animals (meat)

Food Chain Members


Food chain members11 l.jpg

Omnivore

Animals that eat plants and other animals

Food Chain Members


Food chain members12 l.jpg

Producer

Organisms that make their own food (plants)

Food Chain Members


Food chain members13 l.jpg

Consumer

Living things that don’t make their own food

Food Chain Members


Food chain members14 l.jpg

Autotroph

Producer (plant)

Food Chain Members


Food chain members15 l.jpg

Heterotroph

Consumer (animals, fungus)

Food Chain Members


Food chain members16 l.jpg

Decomposer

Organisms that break down dead organisms

ex: fungus, bacteria

Food Chain Members



How would you label the members of this food chain l.jpg
How would you label the members of this food chain?

  • Sun---> grass----> rabbit--->hawk-->fungus

Producer Autotroph

Consumer Heterotroph Herbivore

Consumer Heterotroph Carnivore

Consumer Heterotroph Decomposer

Energy Source


How would you label the members of this food chain what members are missing l.jpg

Consumer Heterotroph Carnivore

How would you label the members of this food chain? What members are missing?

Consumer Heterotroph Carnivore

Consumer Heterotroph Herbivore

Producer Autotroph


Create a food chain with the following organisms l.jpg
Create a food chain with the following organisms:

  • Field mouse, sun, bobcat, bacteria, snake, clover

  • Sun--> clover--> field mouse--> snake--> bobcat---> bacteria


Energy pyramids l.jpg

Energy Pyramid

1. Sun holds 100% of available energy

2. The farther up the food chain you go, the more energy is lost to heat and activity

3. So, the higher you go, the lower the amount of available energy

Energy Pyramids

Assessment most energy found- why?
