Answer:
The correct answer is option A.
Explanation:
Emus are flightless birds that are native to the African part of the geological location. It is the second largest bird on the planet that can not fly but run very fast.
They show similarities with their Australian cousin ostriches. Ostriches are found in Australia, these are the largest bird on the planet. These are also flightless birds and run up to 45 MPH.
Thus, the correct answer is option A.
The right options are; makes food for all organisms, adds oxygen to the atmosphere, is a source of medicines and fibers, is a source of building materials and it provides animal habitat.
Photosynthesis is a process by which green plants and some other autotrophs use light energy in chloroplasts to generate carbohydrates (food) from carbon dioxide and water while oxygen is being released as a by-product. Photosynthesis is essential to all living organisms on earth because it is the main source of oxygen in the atmosphere. Photosynthesis provides animal habitat, it provides food for all organisms (directly for plants and indirectly for animals). Plants and trees produce their foods through photosynthesis and are used as medicines and fibers, and as building materials.
Answer:
option B: one species decreases the probability that a second species will become established
Explanation:
Inhibition as a mechanism of succession occurs when some early species which could also include pioneer species make the site less suitable for the development of other species and do not allow them to become established and grow. When eventually these early species die, other species that were hindered will subsequently grow and become established gradually giving rise to a climax community.
Greenhouse gases arise naturally, and are part of the make-up of our atmosphere. Earths conditions are just right to allow life, including us, to flourish. Part of what makes Earth so amenable is the naturally-arising greenhouse effect, which keeps the planet at a friendly 15 °C (59 °F) on average. But in the last century or so, humans have been interfering with the energy balance of the planet, mainly through the burning of fossil fuels that give off additional carbon dioxide into the air. The level of carbon dioxide in Earth’s atmosphere has been rising consistently for decades and traps extra heat near the surface of the Earth, causing temperatures to rise.
