Question

Savannah are
$1)$ Tropical rainforest
$2)$ Dessert
$3)$ Grassland with scattered trees
$4)$ Dense forest with close canopy

Answer 1

Hint: Savannas are often defined by seasonal water availability, with the majority of rainfall falling within a single season; they are found in a variety of biomes and are frequently found in a transitional zone between forest and desert.

Complete answer:
Option $1$: This is not the correct option because rainforests are forests that receive a lot of rain on a regular basis, with annual rainfall ranging between $2.5$ and $4.5$ meters in tropical rainforests and varying by area in temperate rainforests whereas Savannas are found where there is less rainfall.

Option $2:$ This is not the correct option because Savanna is found with trees or clumps of trees that are widely distributed whereas desert is an ecosystem in which plant growth is restricted by a lack of precipitation; deserts can be found in both temperate and tropical climates.

Option $3$: This is the correct option because A savanna, also known as a savannah, is a mixed woodland-grassland habitat of trees that are sufficiently spaced so that the canopy does not close. The open canopy allows enough light to reach the ground to sustain a continuous herbaceous layer dominated by grasses. The African savanna biome is a tropical grassland with warm temperatures all year and the most rainfall during the summer. The grasses and small or scattered trees that make up the savanna do not form a closed canopy, enabling sunlight to reach the ground.

Option $4$: This is not the correct option because despite high tree density, savannas retain an open canopy. It's a common misconception that savannas have a lot of trees that are all over the place. Tree densities are higher and trees are more evenly distributed in many savannas than they are in forests.

Option $3$ is the correct answer.

Note: Savannas are mainly grasslands with a few scattered trees. They encircle half of Africa, as well as vast swaths of Australia, South America, and India. Climate change, soil conditions, animal behaviour, and agricultural practices may all contribute to the formation of savannas.
