Easiest way to understand it:

Think of it like this:

Just like you came from your parents, every living thing comes from other living things.

Without reproduction, no plants, animals, or humans would exist today.

---

Two main types of reproduction

1. Asexual reproduction (one parent)

4

• Only one parent is needed
• Offspring are exact copies of the parent
• Happens in simple organisms like bacteria, amoeba, some plants

Example:
A bacteria splits into two two identical bacteria are formed.

---

2. Sexual reproduction (two parents)

5

• Two parents are involved (male + female)
• Male and female cells join together
• Offspring is a mix of both parents

Example:
In humans, sperm + egg combine baby is formed.

---

One-line memory trick:

• Asexual = one parent = copy
• Sexual = two parents = mix

This question is of science in biology class 8

Science is a systematic,evidence-based method of observing, experiment,and understanding the natural world .

Breathing is a physical process. Breathing is a continuous process that involves both inhalation and exhalation.Breathing is a part of respiration. Respiration is a process in which food broken down into the cells to release energy is know as respiration. Respiration is a biochemical process. It’s involves the release of energy.

Herbivores Consume producers like plant which contains cellulose in the cell wall of their cells Digestion of the cellulose in the gut takes a longer time and hence, the gut of herbivores is longer than gut of carnivores

These notes explain the concept of life processes, including nutrition, respiration, transportation, and excretion. They describe how living organisms perform essential functions to maintain life and survive in their environment.
