Explanation:

Question 2

Desert ecosystems have extreme heat during the day, so plants (like cacti) store water, and animals are active at night to avoid heat. Forests, oceans, and estuaries don't have this adaptation.

In the food chain grass → rabbit → hawk, if rabbits (prey) decrease, grass (producer) increases (less consumption), and hawks (predator) decrease (less food). So grass increases, rabbit decreases, hawk decreases.

• Producers: Make food via photosynthesis (water lily, cattail, phytoplankton).
• Consumers: Eat others (fish, insects, frogs).
• Decomposers: Break down matter (bacteria, fungi).

So:

• Producers (star): water lily, cattail, phytoplankton
• Consumers (cross out): fish, insects, frogs
• Decomposers (circle): bacteria, fungi

(Note: Original marks had errors—bacteria/fungi are decomposers, not producers; phytoplankton is a producer.)

Question (Rivers/Streams & Fish)

(Assuming options: A. Water moves, brings O₂/nutrients; B. Water is salty; C. Water is still...)

Answer:

A. Desert
