Based on the food web diagram, label the following statements as true or false. Drag "True" or "False" to the end of each statem
inessss [21]

Answer:

Phytoplanktons are producers

Squid are secondary consumers

Leopard seals are quaternary consumer

Explanation:

Phytoplanktons are producers because this are small plants that produce their own food by the process know as photosynthesis

Consumers are organisms that depends on plants for survival. They cannot produce their own food like plants. Fish are primary consumers because they eat plants. When Squids eat fish , squid is considered a secondary consumer because they eat  the primary consumer.

Leopard seals are quaternary consumer because they are at the top of the food chain or the tertiary consumer. They eat the primary and the secondary consumer

using the food web, describe two complete food chains that include a ptoducer, consumer, and descomposer.​
Damm [24]

Answer:

A food chain is a representation of what eats what in an ecosystem.

A combination of food chains is termed as a food web.

Example of two food chains in a food web are :

Example No 1:

Plant----- Grasshopper------ Frog---snake--- bacteria

Example No 2:

Plant---- rabbits---- fox---- bacteria

In a food chain, producers are usually plants and algae which are able to make their own food. Consumers feed on the plants. In example no 1, grasshoppers are primary consumers, frogs are secondary consumers, snakes are tertiary consumers.

In example no 2,plants are producers, rabbits are primary consumers and foxed are secondary consumers.

Decomposers are organisms that feed on the dead organisms in a food chain. In both the examples of food chain, bacteria are the decomposers.

Which hypothesis helps to explain why all organisms share the same genetic code?
KonstantinChe [14]

Answer:

There are two possible answers: Deep-sea vents provided the energy needed for the first organic compounds to form OR self-replicating RNA molecules passed on genetic information.

Explanation:

The reason for the first answer is due to the hypothesis that indicates that life (organic molecules) arose from inorganic molecules synthesized from the amino acids in those energy vents. This is called the metabolism first hypothesis. The Miller-Urey Experiment provided evidence that organisms could rise from inorganic molecules (they simulated under the conditions you would see on early Earth). The second hypothesis is the RNA World hypothesis (second answer) which suggests that the formation of RNA that could replicate (possible due to mutation or evolution), led to life that could preserve its genetic integrity through replication (greater stability to the organism) and create lipid bi-layer membranes/other organelles. Some scientists support the Metabolism First Hypothesis, while others are skeptical (this goes for the RNA World Hypothesis as well). However, the RNA World Hypothesis is for more reasonable in the fact that its main point is the fact that RNA molecules were able to replicate and maintain genetic stability despite early Earth conditions. Although either hypothesis could explain why all organisms share the same genetic code, the RNA World Hypothesis better explains the universality of DNA/RNA of genes that we see today.

How much carbon (in g/m2) is released into the atmosphere as a result of the metabolic activity of herbivores? give your answer
yuradex [85]
I think about 60 g/m^2 is released into the atmosphere as a result of the metabolic activity of herbivores. Metabolism is the sum of the chemical reactions that take place within a cell of a living organisms and that provide energy energy for vital processes and also for synthesizing new organic material. In herbivores, cellular respiration is the major process that releases carbon dioxide in the atmosphere.
