Answer:
1.) The difference between a natural ecosystem from a man-made ecosystem is a natural ecosystem is the result of interactions between organisms and the environment. An artificial ecosystem is not self-sustaining, and the ecosystem would perish without human assistance. For example, a farm is an artificial ecosystem that consists of plants and species outside their natural habitat.
2.) For instance, tropical forests are ecosystems made up of living beings such as trees, plants, animals, insects and micro-organisms that are in constant interaction between themselves and that are affected by other physical (sun, temperature) or chemical (oxygen or nutrients) components.
3.) The COVID-19 pandemic may have implications over the short and long term for food loss and waste. Supply chain losses may increase in the short-term because of logistical bottlenecks and a contraction in the demand for perishables that are often consumed away from home (e.g. milk, eggs and fresh fish). Consumer waste may be increased by hoarding and panic buying, although most of these purchases have been for longer life items, such as flour and pasta. Conversely, restaurant waste, e.g. from the need to offer menu choices, will have been eliminated. Over the longer term the food sector may identify better ways to manage inventories, and consumers may also reassess their shopping and consumption habits, with a view to reducing waste.
