Sally bought some bird seed for the birds in her backyard. she noticed that the cardinals were not eating any of the seeds she put in the bird feeder. what would be a testable question sally could ask about the cardinals' feeding habits? a) how much do cardinals eat in one day? b) cardinals like sunflower seeds the best. c) what kind of seeds do cardinals like to eat best? d) why do cardinals like one kind of seed more than others?

The correct answer is C) What kind of seeds do cardinals like to eat best?

Explanation:

In science, a testable question is a question that can be answered through experiments or tests, and by following the scientific method. In the case of Sally, the best question for her is "What kind of seeds do cardinals like to eat best?" because this question addresses the main phenomenon she wants to study that is the cardinals' feeding habits or what cardinals eat. Also, this question is testable because Sally can discover the answer by placing different kinds of seeds and observing which ones Cardinals choose.

option c 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.
