Answer 1

Ans.

1. GMO corn is genetically modified but golden bantam heirloom corn is non-GMO corn.
2. Predation is a biological interaction where a predator (an organism that is hunting) feeds on its prey (the organism that is attacked). The predator kills the prey at once and has it in the form of food whereas parasite lives in or on another organism (its host) and benefits by deriving nutrients at the other's expense. This type of interaction is called as parasitism. One of the partners is benefitted while the other partner is harmed.

• Examples - lion attacks zebra Is predation ,tapeworm In intenstine of cow is  parasitism.
• 3.The soil of desert regions are dry and mostly made out of sand. And this type of soil is not fertile at all. But,the soil of the grassland is fertile and contains enough amount of moisture and other necessary soil nutrients.

Ans.2) Grassland-  Some grasslands occur in temperate areas of the earth and some occur in tropical regions.

• usually possess deep, rich soil.
• have hot summers cold winters and irregular rainfall.
• Often they are characterized by high winds.
• The main grasslands include the prairies of Canada and USA , the pampas of South America, the steppes of Europe and Asia, and the veldts of Africa.
• The dominant plant species comprise short and tall grasses. In tall-grasses prairies in the United States, important grasses are tall bluestem, Indian grass and slough grass.
• The main animals of this biome are-the prong-horned antelopes, bison, wild horse, jack rabbit, ground squirrel and prairie dogs.

Desert- The desert biome is characterised by its very low rainfall, which is usually 25 cm per year or less.

• Primarily the deserts of the world are located in the south-west U.S.A., Mexico, Chile, Peru, North Africa (Sahara desert), Asia (Tibet Gobi Thar) and central Western Australia.
• Deserts generally have hot days and cold nights, and they often have high winds.difference of temperature between day and night is due to the lack of water vapour in the air.
• important desert plants are—yuccas, acacias, euphorbias, cacti, many other succulents and hardy grasses.
• desert animals are the herbivorous kangaroo, rat, ground squirrel, and jack rabbit, also reptiles.
