A cousin who has been traveling overseas sneaks a plant through customs (who help along with the USDA, help to prevent invasive
Reil [10]

Answer and Explanation:

Invasive species are not native to an ecosystem/environment to which they've been introduced, which can cause disastrous disruptions to various food chains/webs and other native species' populations.

In this case, your cousin is bringing in a plant from overseas, so it clearly will be an invasive plant. You can tell them the following:

- this plant may take over the feeding source of native plants, causing those populations to decrease drastically or possibly even be wiped out

- secondary consumers that had once relied on those native plants for food energy will now have limited resources, competition will increase, and these consumers may begin to die off

- tertiary consumers that consumed these secondary consumers will begin to die off, as well

- this chain reaction will ripple through the entire food chain and food web, and totally disrupt the existing ecosystem

Thus, your cousin shouldn't plant this organism in their backyard and should instead destroy it.

What are carbon dioxide in cellular respiration reaction. NEED HELP ASAP!!!
marissa [1.9K]

Answer:

Microorganisms such as cyanobacteria can trap the energy in sunlight through the process of photosynthesis and store it in the chemical bonds of carbohydrate molecules. The principal carbohydrate formed in photosynthesis is glucose. Other types of microorganisms such as nonphotosynthetic bacteria, fungi, and protozoa are unable to perform this process. Therefore, these organisms must rely upon preformed carbohydrates in the environment to obtain the energy necessary for their metabolic processes.

Cellular respiration is the process by which microorganisms obtain the energy available in carbohydrates. They take the carbohydrates into their cytoplasm, and through a complex series of metabolic processes, they break down the carbohydrate and release the energy. The energy is generally not needed immediately, so it is used to combine ADP with phosphate ions to form ATP molecules. During the process of cellular respiration, carbon dioxide is given off as a waste product. This carbon dioxide can be used by photosynthesizing cells to form new carbohydrates. Also in the process of cellular respiration, oxygen gas is required to serve as an acceptor of electrons. This oxygen gas is identical to the oxygen gas given off in photosynthesis.
