  4. Rapid housing
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

An ecosystem can be defined as a biological community with interacting organism and their physical environment. Though urbanization and industrialization may disturb the ecosystem to an extent, introduction of toxins into environment will spoil the ecosystem from its roots.

How are the wild animals affected by cutting of forest?

  1. Number decreases

  2. Color of skin will be affected

  3. Ability of homeostasis will decrease

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Seventy percent of the world's plants and animals live in forests and are losing their habitats to deforestation (cutting of forest), Loss of habitat can lead to species extinction. The number of wild animals decreases by cutting of forest because If the trees are gone, birds, reptiles, and insects lose their homes and food sources. That will affect the small mammals, which are a food source for mid- and large-sized mammals. It is a cascade effect that leads to species extinction. So, the correct answer is 'Number decreases'.

Multiple choice botany adaptations to different ecosystems lichen lichens lichens ( the nature's pioneers )

Lichens are not found in _________?

Over 230 species of birds are known to be resident. It is also a major tourist centre with scores of ornithologists arriving here in the hibernal season. It was declared a protected sanctuary in 1971. It is also a World Heritage Site.

Keoladeo Ghana National Park is a man-made and man-managed wetland and one of the national parks of India. The reserve protects Bharatpur from frequent floods, provides grazing grounds for village cattle, and earlier was primarily used as a waterfowl hunting ground. The 29 km2 (11 sq mi) reserve is locally known as Ghana, and is a mosaic of dry grasslands, woodlands, woodland swamps and wetlands. These diverse habitats are home to 366 bird species, 379 floral species, 50 species of fish, 13 species of snakes, 5 species of lizards, 7 amphibian species, 7 turtle species and a variety of other invertebrates. Every year thousands of migratory waterfowl visit the park for wintering and breeding. The sanctuary is one of the richest bird areas in the world and is known for nesting of resident birds and visiting migratory birds including water birds. The rare Siberian cranes used to winter in this park but this central population is now extinct. According to founder of the World Wildlife Fund Peter Scott, Keoladeo National Park is one of the world’s best bird areas.
