The whales need your help!
You and your classmates are going on a field trip to Cape Cod. Everyone gets on a boat to watch the whales. While on the boat, you see not only the endangered right whales, but also many different species including tuna, sharks, and seabirds. Your teacher explains that the whales feed on zooplankton and krill. She also says there are less whales coming back each year. Therefore, there might be no whales coming back the following year. Oh, no! Why?! You really like whales and you wonder if you can do something to make them return. You and your fellow explorers decide to investigate.
Questions:
1. Identify the producers and consumers mentioned in the paragraph and write them down.
2. Think of other producers and consumers that could be present in this ecosystem and write them down.
Identify the decomposers mentioned in the story. If there are no decomposers, think of any that could be present in this ecosystem and write them down.
3. Sketch a possible food chain that includes your main organism.
4. Think of what went wrong with this ecosystem. Why and how is the lack of your main organism affecting the rest of the ecosystem?
5. Why are the plants important in this ecosystem? From where they get their energy?
the one who will answer correctly will be marked as brillianest.
Answers
2) •Micro-organisms that break down the complex organic compounds present in dead plants and animals and their products, such as faeces and urine, into simpler substances are called decomposers. Bacteria are decomposers.
•Decomposers decompose dead plants and animals and hence act as cleansing agents of the environment.
4) Virtually all of Earth’s ecosystems have been significantly transformed through human actions. Changes have been especially rapid in the last 50 years and today the fastest changes are taking place in developing countries. Ecosystems are particularly affected by large-scale fishing, freshwater use, and agriculture.
Ecosystems depend on fundamental environmental cycles such as the continuous circulation of water, carbon, and other nutrients. Human activities have modified these cycles, especially during the last 50 years, through increases in freshwater use, carbon dioxide emissions, and fertilizer use. This in turn has affected the ability of ecosystems to provide benefits to humans
