Answer 1

Explanation:

nitrogen fixing organisms, their mode of living

The symbiotic nitrogen-fixing bacteria invade the root hairs of host plants, where they multiply and stimulate formation of root nodules, enlargements of plant cells and bacteria in intimate association. Within the nodules the bacteria convert free nitrogen to ammonia, which the host plant utilizes for its development.

ecological and economic significance.

Ecological economics recognises local to global environmental limits. It ranges from research for short-term policy and local challenges through to long-term visions of sustainable societies. Ecological economists also consider global issues such as carbon emissions, deforestation, overfishing and species extinctions
