The graph shows the average annual water temperature in holbrook pond. which part of the graph shows the steepest increase in the pond’s temperature?

The top portion of the crest

Explanation:

In the given graph, the temperature of the pond has increased by the highest degrees while moving from second colored box to third colored box, thus it shows the steepest increase in the pond’s temperature

If we look at the temperature increase at each red box , we will get the following

Temperature at red box 1 – 5 degree celcius

Temperature at red box 2 – 12.5 degree celcius, thus the temperature rose by 7.5 degrees while moving from box 1 to box 2

Temperature at red box 3- 22.5 degree celcius, thus the temperature rose by 10 degrees while moving from box 2 to box 3

After this the temperature starts falling.  

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.
