Complete the table: Write the information about various components of the forest. Producers Primary consumers Secondary consumers Tertiary consumers Decomposers Dipterocarpus , Teak, Pine, Sandalwood Ant, Grasshopper, Spider, Butterfly Snake, Bird, Lizard, Jackal Tiger, Falcon, Cheetah Aspergillus, Polycarpus

Producers Primary consumers Secondary consumers Tertiary consumers Decomposers Dipterocarpus , Teak, Pine, Sandalwood The green plant in the ecosystem are called producers. They carry out the process of photosynthesis. Ant, Grasshopper, Spider, Butterfly They are herbivores and feed on plants and their products. Snake, Bird, Lizard, Jackal The consumers that feed on these herbivores are carnivores, or more correctly primary carnivores (though secondary consumers). Tiger, Falcon, Cheetah Animals that depend on the primary carnivores for food are labelled secondary carnivores. Aspergillus, Polycarpus Decomposers secrete digestive enzymes that breakdown dead and waste materials into simple, inorganic materials, which are subsequently absorbed by them.

Match the following. Producers Ecosystem a. Cactus 1. Forest b. Aquatic plants 2. Creek c. Mangroves 3. Aquatic d. Pine 4. Desert

a - 4 Cactus has its leaves modified as spines to prevent the loss of water in dry conditions. It is found in the desert ecosystem. b - 3 The plants which are present in the water are called aquatic plants. They are found in the aquatic ecosystem. c - 2 The small shrubs and trees found near the saline water are called mangroves. The ecosystem where mangroves are found includes the creek, a natural stream of water that is smaller than a river or like a tributary. d - 1 Pines are cone-shaped trees found in a cold climate. These are present in the forest ecosystem of the mountains. Producers Ecosystem a. Cactus 4. Desert b. Aquatic plants 3. Aquatic c. Mangroves 2. Creek d. Pine 1. Forest
