conduct research on the types of organisms that live in the ecosystem you choose -
Ecosystems, or biological communities, comprise both living organisms such as animals, plants, insects, and microorganisms and nonliving components such as rocks, soil, water, and sunshine.
- Producers are plants and algae that manufacture their own sustenance.
- Herbivores eat plants and are classified as main consumers.
- Secondary consumers are carnivores that devour herbivores at the third level.
- Tertiary consumers are predators that consume other carnivores.

Answer:
D. Population genetics
Population genetics is the study of genetic variation within populations, and involves the examination and modelling of changes in the frequencies of genes and alleles in populations over space and time. ... In natural populations, however, the genetic composition of a population's gene pool may change over time.
Explanation:
microevolution - evolutionary change within a species or small group of organisms, especially over a short period. (Not studying the overall evolution in the population, just a single allele usually) Not it then
macroevolution - Macroevolution in the modern sense is evolution that is guided by selection among interspecific variation, as opposed to selection among intraspecific variation in microevolution (this goes over huge groups of different species) Not it then
gene pool - The gene pool is the set of all genes, or genetic information, in any population, usually of a particular species. (Not the study of evolution in a population) Not that then
So it has to be D
In physics, escape velocity is the speed where the kinetic energy of an object is equal to the magnitude of its gravitational potential energy.
This relates to the speed at which an object should travel to "break" free of any gravitational pull.
Venus: 10.46 km/s
Mars: 5.027 km/s
Answers;
Do not plow when extremely heavy rains are expected
Plant trees to shield field from the wind
Keep plants growing.
Explanation;
Soil erosion is the wearing away of a field's top soil by the natural physical forces of water and wind or through forces associated with farming activities. Preventing top soil erosion is critical in agriculture; this is normally done using various measures such as Planting grass and shrubs, mulching, avoid soil compaction among other methods.
