As energy is transferred through an ecosystem, not all trophic levels receive the same amount. The marine ecosystem consists of primary producers like phytoplanktons; primary consumers like zooplanktons, krill; secondary consumers like leopard seals; and tertiary consumers like killer whales.
Explanation:
In an oceanic or marine ecosystem, the leopard seals are secondary consumers. They basically feed on the primary consumers. They are eaten up by the tertiary consumers. The prey animals of leopard seal includes primary consumers like small fishes, zooplanktons, coral polyps, krill etc. The energy level in the food web increases in a top to down pattern. The producers which occupy the base level will be with high energy and going up the food web, the energy will decrease subsequently. Leopard seals are huge and eat

Answer:
A. Both in mitosis and meiosis (II)
B. Mitosis
C. In both
D. Meiosis
E. Mitosis
Explanation:
Prior to every case of cell division in both mitosis and meiosis, the cell always ensures to duplicates its contents including its chromosomes. In both cases of cell division, the sister chromatids separates, apart from in meiosis I where homologous chromosomes separates to opposite poles. Only one cellular division occurs in mitosis which is involved in the growth and development of the diploid individual but in meiosis, two divisions takes place in the gametes (both male and female) to ensure that the haploid number of chromosomes is transfered from both parents each to the offspring ensuring a constant diploid offspring. Thus a diploid parent cell always produces a haploid daughter cell in the gametes during meiosis. In mitosis, the daughter cells are always identical to the parents cells.
Evolution is caused by genetic mutations that become favorable for survival.
For example if a bird has a mutation that gives it a longer beak and it lives in an environment in which a longer beak lets the bird catch more food- the longer beak becomes a favorable trait.
Now the bird is able to survive “better” thus it lives longer(due to its ability to catch more food). Because of this it reproduces more and passes the trait on to its offspring.
Overtime this mutation takes over the population of birds in the area.
