What is the correct order of soil layers from bottom to top?

• organic, topsoil, subsoil, parent rock, bedrock

• bedrock, parent rock, subsoil, topsoil, organic

• topsoil, organic, subsoil, bedrock, parent rock

• bedrock, subsoil, parent rock, organic, topsoil

Answer explanation

Hydrotropism and _______ work together and are difficult to separate from one another.

• thigmotropism

• phototropism

• gravitropism

• nastic movements

Answer explanation

Hydrotropism and gravitropism work together and are difficult to separate from one another.

Which non-mineral nutrients are essential in photosynthesis? (Select all that apply.)

• hydrogen

• calcium

• carbon

• oxygen

Answer explanation

The Non-Mineral Nutrients are hydrogen (H), oxygen (O), & carbon (C). These nutrients are found in the air and water. In a process called photosynthesis, plants use energy from the sun to change carbon dioxide (CO₂ - carbon and oxygen) and water (H₂O - hydrogen and oxygen) into starches and sugars.

Which of these are examples of positive tropism? (Select all that apply.)

• a plant’s roots growing down into the soil due to gravitropism

• a plant’s leaves growing toward the direction of the sun due to phototropism

• a plant’s leaves growing away from the sunlight due to phototropism

• a plant growing away from an object due to thigmotropism

Answer explanation

Growing towards a stimulus = positive

Growing away from a stimulus = negative

 

What is needed in order to have healthy soil?

Answer explanation

Plants require many nutrients, including three primary nutrients: nitrogen, phosphorus, and potassium. Nitrogen is needed for leaf growth, phosphorus for root growth and seed formation, and potassium to maintain overall vitality.
