The correct option is A I and II
I. Tropical rain-forests are rain-forests that occur in areas of tropical rain-forest climate in which there is no dry season – all months have an average precipitation of at least 60 mm – and may also be referred to as lowland equatorial evergreen rain-forest. True rain-forests are typically found between 10 degrees north and south of the equator
II The temperate deciduous forest is a biome that is always changing. It has four distinct seasons: winter, spring, summer, and fall. Winters are cold and summers are warm. Temperate deciduous forests get between 30 and 60 inches of precipitation a year.
III. With over 20,000 known species, the orchid is one of the most common types of flowers found in tropical rainforests. Orchids that search for more sunlight through the dense forest canopy actually grow in the top part of tree branches.
IV. The soil in temperate deciduous forests tends to be deep and rich with a wide variety of nutrients because it receives a new blanket of leaves every autumn. The foliage of low-lying plants dies off and adds its own nutrient characteristics to the soil. During the winter, snow blankets the ground. Beneath its protective layer, bacteria, earthworms, and insects continue to break down the dead vegetation, creating dark humus. Humus is the spongy matter produced when the remains of plants and animals are broken down.
So, the correct statement is “I and II”.
