Question

advantages and disadvantages of Ecology​

Answer 1

Explanation:

Ecology (from Greek: οἶκος, "house", or "environment"; -λογία, "study of")[A] is a branch of biology[1] concerning interactions among organisms and their biophysical environment, which includes both biotic and abiotic components. Topics of interest include the biodiversity, distribution, biomass, and populations of organisms, as well as cooperation and competition within and between species. Ecosystems are dynamically interacting systems of organisms, the communities they make up, and the non-living components of their environment. Ecosystem processes, such as primary production, pedogenesis, nutrient cycling, and niche construction, regulate the flux of energy and matter through an environment. These processes are sustained by organisms with specific life history traits.

Explanation:

Researchers examined the association between child wellbeing and economic status in rich developed societies. An ecological cross sectional study design was used, with 23 of the richest 50 countries in the world included in the analysis. Child wellbeing was measured by the Unicef index of child wellbeing. Three macro-economic measures were used—material living standards (average income), the scale of differentiation in social status (income inequality), and social exclusion (children in relative poverty).1 The overall Unicef index has 40 items that measure six dimensions—material wellbeing, health and safety, education, peer and family relationships, behaviours and risks, and young people’s own subjective sense of wellbeing. An item measuring relative poverty was removed before calculating the index of child wellbeing. Low scores indicated worse outcomes. Income inequality was measured as the ratio of the total annual household income received by the richest 20% of the population to that received by the poorest 20%. Therefore, larger values indicated greater inequality between the richest and poorest within a country. Child relative poverty was measured as the proportion of children aged 0-17 years in households with an income equivalent to less than the national median. It was reported that the overall …
