A1. Complete the chart on the life stages of fireflies:(2)
Fireflies are beetles and go through several life stages, starting out as an egg, then hatching into larvae. At the juvenile stage, they turn into pupae and then, finally adults. Fireflies spend most of their lives in a larval stage, hidden away. There are 2000 different species of fireflies. But they all go through a long juvenile stage and a short adult life, which is mainly about courtship, mating and reproduction. The juveniles living underground or underwater, art very different though-they're hunters, they eat snails and soft-bodied insects and they have very different habitats.
Conserving them is essential for human life as fireflies are a key part of the food web. They are predators of agricultural pests. la turn, they are prey for spider and other insects. They are completely enmeshed in the web of life. In addition, about 70 years ago. scientists unravelled the mystery of fireflies' light-producing talents Since then, the bio-chemical reactions that fireflies experience have been used in detecting bacterial contamination in foods, testing drugs against cancer, developing drought-resistant crops. They have even been used in space exploration! So firefiles give us beauty and inventions. Fireflies carry oxygen, calcium, magnesium and a natural chemical called luciferin. These react together to produce the photons. This is how the fireflies glow.
Firefly tourism is growing across the world. In Maharashtra for example, a particular species monsoon fireflies, emerge before the rains. They're beautiful and a festival is held in Purushwadi. encouraging firefly tourism. Its wonderful that people around the world go to see fireflies in their natural habitat. We need to be cautious. Too many people can disturb adult and larval habitats. Fireflies need darkness to communicate with each other and we need fireflies because they are harbingers of hope.
A2. Write two reasons for the conservation of fireflies.
A3. Make antonyms of the following words using prefix:
(1) different x (2) experience x (3) bacterial x (4) natural x
A4. Do as directed:(2)
(1) Too many people can disturb adult and larval habitat. (Rewrite using 'as well as'.)
(2) These react together to produce photons. (Pick out the infinitive from the given sentence.)
A5. Personal Response:(2)
Can you think of any other insect that teaches us some values of life? Explain with examples
[B]. Read the passage given above and write a summary of it in a paragraph. Suggest a suitable title. (5 Marks)
