Darwin concluded that the finches all shared a common ancestor but had developed different beak structures. The second sentence best describes as an ecosystem.
Explanation:
- When Charles Darwin traveled to the Galapagos Islands, he observed 14 distinct varieties of finches on the islands Darwin also observed that each finch variety ate a different type of food and lived in a slightly different habitat from the other finches, Darwin concluded that the finches all shared a common ancestor but had developed different beak structures. The second sentence best describes as an ecosystem.
- An ecosystem is a huge group of living organism such as plants,animals, micro-organisms in a particular area.
- An ecosystem is a community of living organisms related with the nonliving components in the environment, together interacting as a system.

Answer:
The most appropriate answer would be B. Have factories recycle water.
Recycling of water refers to the process which processed the waste water and convert it to reusable form.
It can be reused for various purposes:
- Agriculture: irrigating different types of crops, aquaculture etc
- Urban uses such as irrigating golf courses, public parks, private gardens, roadsides, cleaning of roads, systems involved in fire protection, washing of vehicles, toilet flushing, snow-making etc.
- Industrial uses: processes that involve water like cooling towers, washing, dust control etc.
- Environmental uses: It also helps in recharging the surface and ground water, marshes, wetlands, silviculture, wildlife habitat etc.
- Potable: Recharge aquifers ultimately leads to increase in quantity of drinking water.
Hence, having factories which recycle water helps in keeping the freshwater resources renewable.
