Top 10 Commonly Confused Words in Plant Ecology

Top 10 Commonly Confused Words in Plant Ecology 1. Community vs. Ecosystem Often used interchangeably, 'community' and 'ecosystem' have distinct meanings. A 'community' refers to the various populations of different species coexisting in a specific area. On the other hand, an 'ecosystem' encompasses not just the living organisms but also the non-living components, such as soil, water, and climate. So, while a community is a part of an ecosystem, the latter is a broader concept. 2. Habitat vs. Niche While studying an organism's environment, you'll frequently encounter the terms 'habitat' and 'niche.' A 'habitat' refers to the physical location where an organism resides, including its surroundings. On the other hand, a 'niche' is the role or position that the organism occupies within its habitat, including its interactions with other species and its utilization of resources. So, while a habitat is the 'address,' the niche is the 'occupation' of an organism. 3. Photosynthesis vs. Respiration Both photosynthesis and respiration are vital processes for plants, but they occur in different contexts. 'Photosynthesis' is the process by which plants convert light energy into chemical energy, utilizing carbon dioxide and releasing oxygen. On the other hand, 'respiration' is the process by which plants break down organic compounds to release energy, utilizing oxygen and producing carbon dioxide. In simple terms, photosynthesis is about energy production, while respiration is about energy release. 4. Autotroph vs. Heterotroph
