How is excessive carbon dioxide pollution removed from the atmosphere?

Answers

Answer:

Carbon dioxide removal (CDR), also known as negative CO2 emissions, is a process in which carbon dioxide gas (CO2) is removed from the atmosphere and sequestered for long periods of time. CDR methods include afforestation, agricultural practices that sequester carbon in soils, bio-energy with carbon capture and storage, ocean fertilization, enhanced weathering, and direct air capture when combined with storage. To assess whether net negative emissions are achieved by a particular process, comprehensive life cycle analysis of the process must be performed.

Determine the stability of each ecosystem. 1. an ecosystem with populations that mate with unrelated species. 2. an ecosystem that has very few species at every trophic level. 3. an ecosystem with populations that mate with only related species. 4. an ecosystem that has many species at every trophic level. Less Stable More Stable

Answers

The number of species and the mating patterns of species in an ecosystem will make it either more or less stable.

What is the stability of an ecosystem?

The stability of an ecosystem refers to the ability of that ecosystem to remain relatively unchanged in the composition of both biotic and abiotic factors over a long period of time.

The stability of an ecosystem depends on the changes that occurs in the ecosystem.

Considering the above situations;

an ecosystem with populations that mate with unrelated species will be less stable.an ecosystem that has very few species at every trophic level will be less stable.an ecosystem with populations that mate with only related species will be more stablean ecosystem that has many species at every trophic level will be more stable

Therefore, the number of species and the mating patterns of species in an ecosystem affects the stability of the ecosystem.

The organisms will be classified as producers, primary consumers, and tertiary consumers respectively.

Trophic levels

These are the positions of organisms in the food chain in an ecosystem.

Producers are organisms that produce their own foods by photosynthesis. Thus, oak trees are producers.

Primary consumers feed on producers. Moths feed mostly on plant nectars. Some parasites feed on plants while others feed on animals. Thus, parasites can classify as both primary and secondary consumers while moths can only classify as primary consumers.

Secondary consumers feed on primary consumers. Thus, animal parasites will classify as secondary consumers.

Tertiary consumers are usually predators that feed on other animals. Thus, owls and weasels which are known carnivores will classify as Tertiary consumers.
