Food Chains Fishing. Fishing for food chains is another partner activity! For this one, you’ll want to do some prep ahead of time. Create a set of construction paper organisms (I recommend 15 or 20 cards with an equal number of each type of organism found in food chains) and attach paper clips to each “card.”.

Producers or autotrophs make up the first trophic level of the food chain. They prepare their own food from sunlight, carbon dioxide, and water through photosynthesis. All other organisms in the ecosystem use them for food. Although green plants are the most abundant autotrophs on Earth, algae, phytoplanktons, and autotrophic bacterialiving in volc...
The second trophic level consists of herbivores that depend on producers for food. Cow, deer, elephant, and mice are primary consumers in the grassland ecosystem that consumes grasses, shrubs, and trees. In contrast, many fish and turtles are herbivores in the ocean ecosystem that eat algae and seagrass. In forests, sea urchins act as primary consu...
Secondary consumers are the organisms that reside on the third trophic level and depend on primary consumers for food. They can be carnivores or omnivores. Carnivores eat other animals, whereas omnivores eat both plants and animals. In a desert, a snake is a secondary consumer, eating mice. At the same time, in forests, sea otters are secondary con...
Tertiary consumers eat secondary consumers and are found at the last or the fourth trophic level. In deserts, an owl or an eagle is a tertiary consumer eating a snake. There are more levels of consumers above the tertiary consumers. Apex consumers residing at the top of the food chain are organisms that feed on other consumers for food. Such organi...
This lesson follows the 5-E pattern. Day 1 (50 minutes) features Engage, Explore, and Explain. Day 2 (50 minutes) covers Elaborate and Evaluate. Feel free to take your time with this sequence of activities, turning the lesson into a subunit. The suggested time frames are on the tight side.
The Ultimate Science Fair Project Guide – From Start to Finish. December 30 by STEMMomma. When our daughter entered her first science fair, we kept seeing references to the Internet Public Library Science Fair Project Resource Guide. However, the IPL2 permanently closed… taking the guide with it. Bummer!
At the end of this comprehensive food webs lesson plan, students will be able to diagram the flow of energy through living systems, including food chains and food webs. Students will also be able to describe food webs within marine, freshwater, and terrestrial ecosystems. Each lesson is designed using the 5E method of instruction to ensure ...
Record your food chain in the space below using species names and arrows. Answers will vary, but two possibilities are plantà insectà shrewà serval or plantà insectà warthogà lion. 6. Ecosystems include both biotic (living) and abiotic (nonliving) components that can influence food chains.
