Here are the answers to your Biology questions: c) State four examples of animal habitats. • Forest • Ocean • Desert • Grassland 33a) Define the term respiration. Respiration is the biochemical process by which living organisms release energy from organic molecules (like glucose) to fuel cellular activities. This process can be aerobic (requiring oxygen) or anaerobic (without oxygen). 33b) Give any two adaptations of plants that live in desert habitats. • Thick, waxy cuticle on leaves and stems. • Spines instead of broad leaves. • Deep or widespread root systems. • Succulent stems or leaves for water storage. 33c) Explain how the adaptations mentioned in above question help the plant withstand hazardous conditions of desert. A thick, waxy cuticle* reduces water loss from the plant's surface through evaporation, helping to conserve precious water in arid conditions. Spines instead of broad leaves* minimize the surface area exposed to the sun and wind, significantly reducing water loss via transpiration. Spines also deter herbivores. 34) Study the food web and answer questions that follows. a) Which of the organism is representing first order consumer First-order consumers (primary consumers) feed directly on producers (plants). In this food web, the organisms that eat grass are: • Grasshopper • Bird • Goat b) How can you eradicate the large? Assuming "large" refers to a pest organism in the food web, such as the grasshopper, eradication can be achieved through: • Biological control: Introducing or encouraging natural predators (e.g., snakes or birds that eat grasshoppers) to reduce their population. • Chemical control: Using pesticides to kill the pest directly. • Habitat modification: Removing their food source (grass) or disrupting their breeding grounds.
