a)-iv) A food chain shows the relationship animals in a certain habitat and the food that they eat. Energy gets transferred from one level to other. It is the relationship between animals and the food they eat. b)-viii) These are the organisms which do not make their own food as they are consumers. And are depended on other for energy. c)-ix) Vegetation is an assemblage of plant species and the ground cover they provide. d)-v) Plants are called producers. This is because they produce their own food by using light energy from the sun, carbon dioxide from the air and water from the soil. e)-ii) It is referred to as the protection of something — especially from loss, damage or neglect. Conservation will help in maintaining the biodiversity of an ecosystem. f)-iii) It is the large trees that form an umbrella-like shape. The layer is called the canopy. It is the habitat for numerous animals. g)-x) Forest floor is the last layer. It is dark where sunlight hardly reaches. Mosses and ferns grow here. h) -vi) A food web is the natural interconnection of food chains and is the representation of what-eats-what in an ecological community. i)-vii) It is the clearing process which includes the removal of a forest or stands of trees from the land which is then converted to a non-forest use. j)-i) This is the process by which dead organic substances are broken down into simpler organic or inorganic matter. Decomposers include bacteria and fungi that carry out the process of decomposition. a) food chain iv) the relationship between animals in a habitat and the food they eat b) consumers viii) organisms which do not make their own food c) vegetation ix) the plants of an area or a region d) producer v) organisms which make their own food e) conservation ii) preservation or restoration from loss, damage, or neglect f) canopy iii) a large tree that forms roof over the lower layers g) forest floor x) the lowest layer of the forest h) food web vi) network of interconnecting food chain I) deforestation vii) the clearing of forests j) decomposers i) microorganisms that break down dead plants and animals
