Answer:
- Oak trees: primary producers
- Caterpillars: primary consumers
- Blue Jays: secondary consumers
- Hawks: tertiary consumers
Explanation:
A trophic pyramid, also known as ecological pyramid or energy pyramid, is a graphic representation that shows the relationships between different types of organisms (i.e., producers and consumers) at the trophic levels of an ecosystem. The primary producers are autotrophic organisms that obtain energy from sunlight and chemical compounds from nonliving sources (e.g., photosynthetic plants, algae, etc). The primary consumers are organisms that eat primary producers (e.g., herbivores), while secondary consumers are organisms that eat primary consumers (e.g., omnivores). Moreover, tertiary consumers are predators and/or omnivores that eat secondary consumers (e.g., hawks). Finally, decomposers (e.g., bacteria) are organisms that obtain nutrients and energy by breaking down dead organic material (i.e., dead organisms) at all trophic levels into nutrients.
Answer:
The correct answer will be-
1. Evolutionary unity- DNA
2. specialized cellular modifications- plant cells have chloroplasts and large central vacuole.
Explanation:
<u>Case I
</u>
Evolutionary unity is a concept which explains that all the organisms possess some common structure or universal structure or molecules.
The best characterized evolutionary molecule is DNA molecule which took the role of genetic material in past and is passed on to the daughter cells and still is made up of the same components which are a five-carbon sugar, four types of nitrogenous bases and a phosphate group. This DNA molecule is present in almost every organism except for a few viruses.
<u>Case II
</u>
The specialization of the cellular components depends on the function a cell has to perform which became established in the population. The plant cells depended on the sunlight to prepare food for themselves which was done by the chloroplast organelle which is absent in the animal kingdom.
Answer:
1: Burning of fossil fuel
2: Deforestation
3: Waste disposal in landfills
Explanation:
Burning of fossil fuel is the one of the primary cause of increased level of carbon dioxide in air. Deforestation refers to uncontrolled cutting down of trees which in turn increases the level of carbon dioxide in air. Plants are the natural resources that remove the carbon dioxide from air through the process of photosynthesis. Waste disposals in landfills emits methane which is one of the greenhouse gas.
Answer:
The decrease of a certain good source.
Answer:
Explanation:
The molecule that results from translation is protein -- or more precisely, translation produces short sequences of amino acids called peptides that get stitched together and become proteins. During translation, little protein factories called ribosomes read the messenger RNA sequences.
