Multiple choice

What is the term used for the cultivation of aquatic plants in aquaculture systems?

  1. Aquaponics

  2. Hydroponics

  3. Mariculture

  4. Inland Aquaculture
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Aquaponics is a sustainable farming system that combines aquaculture (fish farming) with hydroponics (plant cultivation in water) to create a symbiotic relationship between the two.

Multiple choice

Which aquaculture technique involves the integration of fish farming with the cultivation of plants, often in a symbiotic relationship?

  1. Aquaponics

  2. Hydroponics

  3. Mariculture

  4. Inland Aquaculture
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Aquaponics combines aquaculture and hydroponics, where the waste from fish farming provides nutrients for plant growth, and the plants help filter and clean the water for the fish.

Multiple choice

What is the primary method of banana propagation?

  1. Seeds

  2. Cuttings

  3. Grafting

  4. Tissue culture
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Bananas are typically propagated through vegetative cuttings, where a section of the rhizome or sucker is planted to produce a new plant. This method allows for the preservation of desirable traits and rapid multiplication of plants.

Multiple choice

D Correct answer
Explanation

Staking, trellising, and caging are all methods used to support climbing vegetables and provide them with a structure to grow on.

Multiple choice

What is the process of thinning out seedlings to ensure proper spacing and growth called?

  1. Transplanting

  2. Thinning

  3. Pruning

  4. Staking
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Thinning is the process of removing excess seedlings from a planting area to ensure proper spacing and growth, allowing the remaining plants to develop and produce a higher yield.
