a. heterotrops
Answer:
Explanation:
a) Plants are called as autotrophs because they fix carbon dioxide.
Autotrophs are any organisms which can produce their own food with the help light energy, water and carbon dioxide.
(b) In an ecosystem dominated by trees, the pyramid (of numbers) is inverted type.
The reason for this is because the number of insects, birds feeding on trees will always exceed the number of trees present. Single tree can give shelter and provide food many of birds and insects.
c) In aquatic ecosystems, the limiting factor for the productivity is light.
Light level is an important factor in aquatic ecosystem. Light is needed by plants for photosynthesis, the process through which plant turns light into energy. Sunlight is important for plants to grow and provide energy. Light intensity controls plant flowering and animal insects habits.
d)Common detritivores in our ecosystem are earthworms.
Detritivores are organisms which cannot produce food by themselves . They get their nutrition by feeding on detritus which is available in the environment. These detritus includes fecal matter, decomposing plant and animal remains.
e) The major reservoir of carbon on earth is oceans
The major reservoir of carbon on the Earth is found in the deep-ocean It stores about 36,000 billion tons of carbon while the combined carbon found on Earth is 65,500 billion tons.
Hope this helps.
