Answer 2

1.Mode of nutrition by killing the host is called predation.

Explanation:

• Scavenging is the main mode of nutrition in which organisms feed on dead organisms.
• The predation (the predator) kills the one organism and feeds on the other organism is called prey.
• The parasitism is known as one organism feeds on the other organism without killing the other organism.

2. If the strongest partner is benefitted and the weak partner is damage , it is known as (d) predation.

Explanation:

• Predator captures the organism, kills the organism and eats another organism, called prey.
• Predators are generally carnivorous animals as well as herbivorous.
• Herbivores that destroy whole plants or seeds are also called predators.

Hence,

1. (a) predation

2. (d) predation
