Answer:
Producers are responsible for providing energy to the rest of the ecosystem.
Explanation:
Producers are literally the basis of all food chains, if they do not exist, it is impossible for energy to pass from one trophic level to the next.
Producers are represented by plants that, through photosynthesis, produce enough energy to be passed to all living organisms, through the food chain. For this reason, it is important to maintain the stability of the producing population, since the stability of the entire ecosystem depends on it, since it is through it that energy is provided for the rest of the ecosystem.
B. The red-tailed hawk is a secondary consumer.
C. The worms are primary producers.
D. Grasshoppers are primary consumers.
Answer:
Grasshoppers are primary consumers.
Explanation:
Autotrophs serve as primary producers in a food chain as they can make organic food by the process of photosynthesis. In the given food chain, tall grass is the primary producer. Grasshoppers derive their nutrition from the tall grass. The organisms that derive nutrition directly from the primary producers are said to be primary consumers. This makes grasshoppers primary consumers.
Mice the secondary consumers as they feed on the grasshoppers, the primary consumers. Red-tailed hawks are the top consumers in the given food chain. The bacteria, beetles, fungi, and worms are the decomposers that derive nutrition from the organic matter present in the dead bodies of the red-tailed hawks.
Answer:
Marine debris consists of most anything used and discarded by humans. Winds, rivers and storms can carry this debris to the ocean from far inland, so it is not solely a case of pollution along shorelines.
Explanation:
The animals and humans contain about 20 different amino acids, which combine in different combinations to form a functional protein.
Further Explanation:
Protein synthesis occurs in the following steps:
1. The DNA sequence present in the gene is converted into the messenger RNA (mRNA) sequence through transcription.
2. This mRNA is then translated into an amino acid sequence by translation resulting in the formation of protein or polypeptide chain.
A nucleotide sequence makes up an mRNA, which is read as a codon sequence. Each codon specifies an amino acid. A codon is a set of three nucleotides, and a complete chain of codons determining the amino acid sequence for a particular protein is called the genetic code.
The proteins are composed of different mixtures of 20 amino acids and are expressed through DNA containing only four nucleotides. The different sets of nucleotides are present in a group of three codes for particular amino acids and are referred to as codons. This combination of nucleotides results in the formation of 64 codons for coding 20 amino acids. Out of 64 codons, three are stop codons while the other 61 codons represent an amino acid.
Each amino acid consists of a carboxyl group which is acidic in nature; it has an organic side chain or R group, and an amino group (basic). The R group is unique or specific for a particular amino acid. All these groups are attached to a carbon atom placed at the center. The amino acids are grouped as essential and non-essential, depending on whether they are obtained from the food sources or made within the body, respectively.
The amino acids are essential for humans as they help in the formation of proteins. These proteins are required for the formation of red blood cells, antibodies, enzymes, transport proteins, hormones, and for growth and repair of the organs and tissues.

Living organisms typically have 20 common amino acids. Nine of these are essential for humans as the body cannot produce them. Amino acid sequences can also inform us about the evolutionary relationships between species.
In living organisms, there are typically 20 common amino acids that are found. These include asparagine, tyrosine, tryptophan and phenylalanine, each with a different R group (variant group) that determines its chemical nature. However, out of these 20, nine are considered essential amino acids in humans because the human body cannot produce them. Therefore, these nine need to be consumed in our diet.
Furthermore, the comparison of amino acid sequences in proteins such as cytochrome c among different species has been a key method to trace evolutionary relationships. In this method, the more amino acid sequence differences there are between two species, the longer ago they are presumed to have diverged from a common ancestor.
