1 Energy

2 Standard and EQ Standard: Essential Question:
SZ4. Students will assess how animals interact with their environment including key adaptations found within animal taxa.  Essential Question: How do organisms interact with one another and how do they obtain energy?

3 I Will Be Able To… Differentiate between autotrophic and heterotrophic
Apply the three types of symbiosis to relationships in nature Explain why organisms use specific adaptations Explain how organisms can occupy multiple trophic levels

4 Symbiotic Relationships Worksheet
Symbiosis is a close, long-term relationship among two or more species that live and interact together Time Limit: 15 minutes 3 Major types of symbiosis Parasitism Mutualism Commensalism

5 Producers Also called autotrophs. Have the most energy.
Greek: Autos: self Trophe: nourishing Have the most energy. Use most of the energy they get for themselves. Some of the energy is released as heat. What happens to the energy that they don’t use?

6 Consumers Also called heterotrophs.
Greek: Heteros: another/different Trophe: nutrition Are not able to make their own energy. Eat producers or other consumers to get energy.

7 Types of Consumers Herbivore - a consumer that only eats plants.
Omnivore - a consumer that eats plants and animals. Carnivore - a consumer that only eats animals.

8 Consumer Specialization
Scavenger - consumers that feeds on dead organisms. Detritivore - consumers that feeds on detritus (waste/debris) and/or decaying organisms. Decomposer - consumers that feeds on decaying organisms via absorbing its nutrients.

9 Types of consumers Primary Secondary Tertiary Quaternary

10 Primary Consumers Herbivores are primary consumers because they only eat plants. Most of the energy it receives from a producer is used.

11 Secondary consumers A consumer that eats primary consumers.
May be a carnivore, omnivore, predator, or scavenger

12 Secondary Consumers: Continued
Most of the energy from the primary consumer is used by the secondary consumer.

13 Tertiary Consumers Consumers that eat secondary consumers.
May be a carnivore, omnivore, predator, or scavenger

14 Quaternary Consumers Consumers that eat tertiary consumers.
May be a carnivore, omnivore, predator, or scavenger, decomposer or detritivore.

15 Food chains Show the transfer of energy from one organism to another.
Arrows represent the direction of energy flow.

16 Trophic level Each stage/level in a food chain or food web.
The first organism is always an autotroph and the remaining organisms are heterotrophs.

17 Key facts about food chains
Predator: consumers that hunt, kill, and eat other consumers Prey: organisms that are hunted, killed, and eaten The arrow will go from the prey to the predator.

18 What is wrong with this food chain?

19 Food Webs Food web: A collection of interconnected food chains.
Organisms can occupy multiple trophic levels (primary, secondary, etc.) at the same time

20 Name ALL of the producers.

21 Name ALL of the primary consumers.

22 Name ALL of the secondary consumers.

23 Name ALL of the tertiary consumers.

24 Name ALL of the herbivores.

25 Name ALL of the carnivores.

26 Name ALL of the omnivores.
