B. Subgroups
<span>When constructing a dichotomous key, the first step is to look at the group of objects or organisms and separate them into two groups based on a single distinguishing characteristic. Then continue to separate each of the groups until each object has its own separate set of characteristics.</span>
Answer: The population size is recorded for each species present in the construction area before and after the building is completed
This method of collecting data will provide the most accurate information about how an ecosystem is being affected by human development because it studies a lot of different species both before and after the construction.
Answer:
Photosynthesis and cellular respiration allow the carbon and oxygen that organisms consume and produce to be cycled through the ecosystem. They work together so that what is made from one process is used in the other. Without them the ecosystem would run out of carbon dioxide and oxygen, and everything would die.

Ecology is the science that studies the interaction between living beings and the environment in which they live.
<h3>How can I help with conservation?</h3>
- Buy recycled paper avoiding the death of more trees
- Have a recycling bin for paper, plastic, metal and glass, to reduce the environmental damage in waste and for the waste to be reused
- Recycle toner and ink cartridges from empty printers, to avoid polluting rivers and streams.
- If possible buy remanufactured cartridges, avoiding environmental impact
- Recycle old newspapers, avoiding the death of more trees.
<h3>What is the evidence for evolution?</h3>
- Anatomy. Species may share similar physical features because those features were present in a common ancestor (homologous structures).
- Molecular biology. DNA and genetic code reflect the common ancestry of life
With this information, we can conclude that Ecology is concerned with the living beings on the planet and their relationships with each other and with the environment.
