Ecology 11/13/14 Learning Intention: We will demonstrate knowledge of the Energy transfer within various ecosystems. Success Criteria: We will be successful when we can interpret these relationships using food webs and energy calculations.

Today’s Agenda Upcoming Review Study Stations

Test tomorrow! Unit 2 Questions from notes Ecosystem organization, trophic levels, food chains, food webs, vocab (Biotic, abiotic, habitat, niche, limiting factor, predator, prey, autotroph, heterotroph, producer, consumer, herbivore, omnivore, carnivore, scavenger, decomposer) Questions about labs (quadrat sampling, owl pellets and food web) FYI microscopes NOT on test

Homework will be collected! Pyramid Ecology review 3 Big questions Vocab

10% Rule Only 10% of the energy from one trophic level is passed on to the next level All other energy is used up or lost to environment as heat

Energy Pyramid: diagram that compares energy used by producers and consumers at different trophic levels. Shows available energy at each level in ecosystem

Pyramid of Numbers: shows the number of individual organisms at each trophic level in an ecosystem

Study Stations Extra notes on PP (Up front) Vocab (D) Extra copies of MAIN set of notes (E) Book problems: (CHAPTER 13) Page 397, #12, 14, 16, 17, 20 Page 399, #2, 4, 5,

All energy comes from the sun Plants harness the sun’s energy through photosynthesis

Producers or Autotrophs are organisms that make their own food by obtaining materials from the environment.

We call plants producers because they produce energy from the sun directly.

Consumers or Heterotrophs are organisms that eats other organisms for food

Consumers In A Food Chain 1º Primary Consumers: eat producers 2º Secondary Consumers: eat primary consumers 3º Tertiary Consumers: eat secondary consumers

Types of Consumers Herbivores- eat only plants Omnivores- eat plants and animals Carnivores- eat only animals Scavengers: eat the remains of a kill Decomposers: eat dead or decaying material

A Basic Food Chain Plants absorb light from the sun, which is turned into energy to grow. We call these producers. The vegetarian animals eat the plants, they are called primary consumers. Secondary consumers prey on primary consumers.

ALGAE SHRIMP FISH SHARK How many words that we learned today can we use to describe the organisms in the food chain above?

Food Web A food web is a series of interacting food chains which show complex feeding relationships.

Note the energy transfer arrows

What happens when the food web gets messed up? What happens if the deer population dramatically declines due to disease? What happens if humans cut down the trees and pave over the grass to build a mall?

What concept are you most struggling with from this unit? *Complete sentences! Have a good rest of your day Success Criteria Question Ecology 11/11/14
