Broad-leafed trees in temperature zone lose their leaves? a. to survive the extreme temperature of summer. b.to survive a lack of rain in the dry season. c.to survive colder seasonal temperatures. d.to allow for greater penetration of sunlight.

The correct answer is option c-to survive colder seasonal temperatures.

Explanation:

Broad leafed trees shed their leaves in autumn or winter season which is experienced with colder temperature.

These leaves are called deciduous leaves and shed their leaves because these leaves lack wax coating and anti-freeze chemicals due to which the fluid which flows through veins can be freeze by cold temperature so, plants to save the energy get rid of them.

Thus, option c-to survive colder seasonal temperatures is the correct answer.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
