Assignment 1:

_____ 1. Biotic factors include sunlight, soil, temperature, and water. 

_____ 2. Like nutrients and water, energy also recycles through an ecosystem. 

_____ 3. An ecosystem consists of all the biotic and abiotic factors in an area and their interactions.

Assignment 3:

1. What is shown in this picture, is it a habitat or and ecosystem. Please explain your answer in details: THIS IS AN ECOSYSTEM BECAUSE IT CONTAINS BOTH BIOTIC AND ABIOTIC FACTORS.
2. Name 4 abiotic factors that could influence life in this pond and explain why for each one.

• AMOUNT OF SUNLIGHT: INFLUENCES THE AMOUNT OF SUNLIGHT PLANTS CAN DO
• TOXINS: IF THE WATER GETS POLLUTED THIS CAN AFFECTS THE ANIMALS THAT LIVE IN IT
• TEMPERATURE: IF THE WATER GETS TOO HOT OR TOO COLD THIS COULD AFFECT THE ORGANISMS LIVING IN IT.
• SPACE: IS THERE ENOUGH SPACE FOR ALL POPULATIONS TO EXPAND OR WILL THIS BE AT THE COST OF ANOTHER SPECIES

• 3. Each organism has a niche within the pond, choose 4 organisms and look up what their niche is.
• YELLOW WATERLILY: does photosynthesis and provide shelter for smaller animals.
• NYMPH: later becomes a dragonfly, but is also a food source for tadpoles and froglets.
• RAMSHORN SNAIL: removes waste from pond bottom and is a food supply for the newts and perch.
• WATER SCORPION: Water scorpions directly help ecosystems by controlling smaller insect populations.
