EVERYDAY SCIENCE

Detailed explanation-1: -Plant ecology examines the relationships of plants with the physical and biotic environment. Plants, as sessile and photosynthetic organisms, must attain their light, water and nutrient resources directly from the environment. Light is their source of energy and it is unidirectional in origin.

Detailed explanation-2: -Ecology is the study of how organisms interact with one another and with their physical environment. The distribution and abundance of organisms on Earth is shaped by both biotic, living-organism-related, and abiotic, nonliving or physical, factors.

Detailed explanation-3: -Ecology is the study of the relationships between living organisms, including humans, and their physical environment; it seeks to understand the vital connections between plants and animals and the world around them.

Detailed explanation-4: -In plant communities each plant might interact in a positive, negative, or neutral manner. Plants often directly or indirectly alter the availability of resources and the physical habitat around them. Trees cast shade, moderate temperature and humidity, alter penetration of rain, aerate soil, and modify soil texture.

Detailed explanation-5: -Phytogeography is the study of the distribution of plants or taxonomic groups of plants and its focus is to explain the ranges of plants in terms of their origin, dispersal, and evolution (Matthews et al., 2003).
