Embibe Experts Solutions for Chapter: Weather, Climate and Adaptations of Animals to Climate, Exercise 1: Exercise

Some regions use the xerophytic plant agave as a barrier around farming fields. Actually, those are not desert regions. How can they grow there?

Habitats filled with water are called aquatic habitats. If the water is freshwater then it is called freshwater habitat. If the aquatic habitat has marine or salt water then it is called marine habitat. More than 70% of the surface of the Earth is covered by water. Oceans do have a variety of plants and animals. Marine plants include marine algae, sea grass, marsh grass and phytoplankton.

Marine fishes drink more water than freshwater fishs. Do you agree? Justify

Organisms of the oceans have a lesser salt content in their bodies than the seawater which has around 3.5%. The fluid could drain out of the body of the organism into the sea. This could be dangerous and fatal to the organism. Still, they are surviving in this environment. How? Do they have different kind of adaptation? Explain your answer.

The polar regions present an extreme climate. These regions are covered with snow and it is very cold for the most part of the year. For six months the sun does not set at the poles while for the other six months the sun does not rise. Plants that live in the Polar regions have needle-shaped leaves that prevent water loss through transpiration, they are generally cone-shaped trees so that the snow slides off.

If the trees have broad leaves at the time of snowfall season, what will happen?

The above flow chart represents adaptation for the polar bear. Go through the flow chart and add necessary content for A,B, C and D.

Camouflage is a type of colouration or pattern that helps some animals to blend in with their surroundings. It is an example of adaptation. It is used by many organisms to defend themselves from their predators. It increases the chance of survival of an organism in a particular habitat. If a rabbit lives in a Himalayan regions what colour will suit it most to hide from its predator? Explain your answer.

Report 1: Isolated rain or thundershowers are lightly to occur over Chittoor, Nellore, Prakasham and some parts of Kadapa districts. Mainly dry weather will prevail over southern Telangana districts and northern coastal districts of Andhra Pradesh. The sky may be cloudy for the next two days in Kurnool and Ananthapur districts.

Report 2: According to the meteorological department report 42 °C maximum temperature was recorded at Ramagundam of Peddapalli district and 29 °C minimum temperature recorded at Arogyavaram of Chittoor district. Because of cumulonimbus clouds, 2mm of rainfall was recorded in Hyderabad. Scattered rainfall recorded in some parts of interior Rayalaseema. Remaining part of Telangana and the Andhra Pradesh States was dry.

What aspects of the weather are discussed in both reports? Which report explains what will happen?
