What do you think would happen if there was a sudden decrease in the number of berries in the ecosystem this food web represents?

If this happened, that animal that ate the berries would slowly depopulate causing them to die off overtime, or making them find an alternative food source.  

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.

if you add everything up correctly you should get 69 i got this because 50 plus 19 is it
