29.Ocean Food Webs

• EQ: What are the different aquatic ecosystems? Why are they so important to life on Earth?

• LT:I can identify the organisms within various trophic levels in aquatic ecosystems (such as estuary, wetlands and oceans) .

• POU: I will differentiate between plankton, nekton, and benthos.

• I will identify the different types of animals in the ocean.

• I will identify key properties of Earth’s oceans.

Welcome! It’s Tuesday 3/11/14

WARM UP:1. What is an ecosystem?

2. What is the difference between a PRODUCER and a PRIMARY CONSUMER?

• Please record your responses at www.goo.gl/vta7d1

The food web show the interactions between organisms in a meadow ecosystem

• Which organism gets food energy directly from both plants and animals?

How are estuaries connected to oceanic organisms?

A. Estuaries provide a nursery grounds for oceanic organisms

B. Estuaries provide sunlight for oceanic organisms.

C. Estuaries provide primary food for oceanic organisms.

D. Estuaries provide excess dissolved oxygen for oceanic organisms

HW: What’s for lunch or dinner?

Create your own food chain based on a recent meal.

Label each item in the meal, diagram where the food item comes from

Label the different trophic levels

Ocean Food Webs 20

Ocean Food Webs20

•Plant life: small, unicellular plant cells, photosynthesizing algae, & seaweeds.

• Animal life: Many different types, sizes, species.

Here is the Energy Web:

Suns Energy

Plants, Algae & Photoplankton (“Producers” - do photosynthesis)

Animals & Zooplankton

(“Consumers” - Eat to get energy)

Types of Animals in the Ocean

• Plankton = Floating animal (usually one to a few cells)

• Nekton = Swimming, maneuvering animals (fish, sharks, seals, etc.)

• Benthos = Bottom dweller (on or in the seafloor)

Plankton

Nekton

Benthos

(ex. Halibut)

Popplet: Create an Ocean Food Web• You need 3 plankton, 3 nekton, and 3

benthos in your food web.• You also need at least one

TERRESTRIAL (a.k.a. land) organism that eats something in your Ocean food web.

• This is due by Friday 3/14/14
