The sun feeds the plants through the process of photosynthesis. the animals gain energy and grow by eating those plants. other animals eat those animals and gain energy and grow. the cycle is never ending and all begins with the sun. without it, the plants and animals wouldnt get food and die off.
Answer:
1. Eukaryotic
2. Eukaryota
Explanation:
1. Eukaryotic- The newly found species has a cell wall and contains membrane-bound organelles. The presence of membrane-bound organelles shows that the cell is a Eukaryotic cell.
2. Eukaryota- the species is single-celled with the presence of cell wall without peptidoglycan. This shows that the species could belong to the Eukaryota domain proposed by Carl Woese.
Thus, 1. Eukaryotic and 2. Eukaryota is the correct answer.
Answer:
D. Supporting
Explanation:
Ecosystem services include provisioning, regulating, culture and supporting services.
Opening of a mineral mine along a small mountain range will affect the supporting services of ecosystem because supporting services deals with soil formation, provision of habitat and nutrition cycle.
Opening of mineral mine will destroy the tosoil, landscape, forests and wildlife of mountain area which affect the supporting services such as habitat and soil formation.
Hence, the correct answer is "D. supporting".
Answer:
C. The chance of survival decreases when there is intraspecific competition for resources among surviving yearlings
Explanation:
The survival rate of the offspring of the fish species will decrease as a result of the huge number of eggs produced giving rise to overpopulation. Pressure will be on the limited available resources. As a result of this, Intraspecific competition would occur as members of the same fish species would compete for the limited resources.
Interference and exploitation competition are two types of Intraspecific competition that can reduce the population size of the fish species.
For Interference competition, the dominant and stronger members would secure adequate supply of the limited resources to detriment of the weaker and less dominant ones. This leads to the death of those members that are weak to compete successfully, thereby leading to a reduction in population size.
In exploitation competition, it involves all individual members of the fish species sharing the limited resources equally, while none of them gets an adequate amount. With time, a great size of the population decrease would be noticed when compared to that of Interference competition.
