Answer:
Every organisms on the planet requires a specific environmental conditions for its growth and survival. If the environmental condition is favorable, the organisms grow fast and if the conditions are not suitable so it adversely affected the organisms. For example, plants grow best at the temperature between 25 to 40 Celsius. If the temperature goes below 25 or above 40, the growth decrease and sometimes the plant dies. So climate and abiotic factors such as temperature, humidity, light intensity etc has a great impact on the organisms.
