Assume that producers in an ecosystem have 1,000,000 kilocalories of energy. How much energy is available to primary
consumers?
5. Which trophic level has the greatest biomass?
Therefore, according to this question, if it is assumed that that producers in an ecosystem have 1,000,000 kilocalories of energy; 10/100 × 1,000,000 = 100,000 kilocalories of energy will be available to primary consumers.
WHAT IS BIOMASS:The total biomass of an organism in each trophic level decreases going up. This is due to the lesser energy transferred from one trophic level to the next. As the trophic level increases, lower energy is available to convert into biomass. Hence, the higher the trophic level, the lower the biomass.Therefore, if this is the case, the producers at the first trophic level will contain the greatest biomass which will decrease as the food chain progresses upwards.

The scientific name of an organism is made up of what two group names?
Answer:
Genus species
Explanation:
Scientists use a special naming system for organisms. It is made up of two words.
The first word is the genus of the organism and the second word is the species of the organism.
The first word, which is the genus, is always capitalized, but the second is not. Both words are italicized if possible, but if you are handwriting the scientific names, an underline suffices.
An example of a scientific name for a house cat is:

and angiosperms are flowering plants with . ( PROTECTED SEEDS)
Sporophytes produce spores for reproduction. In seed plants, the male reproductive structure produces , (MICROSPORES)
and the female reproductive structure produces . (MEGASPORES)
Gametophytes produce (GAMETES)
through the process of . (MITOSIS)
Answers are in the question yw :)
Answer:
I've corrected the relevant part in the false statement to make it true. Please see below:
Gymnosperms and angiosperms, which are seed plants, alternate between (2) generations.
The statement is true. It alternates between haploid and diploid stages.
Gymnosperms are non-flowering plants with EXPOSED SEEDS and angiosperms are flowering plants with PROTECTED SEEDS.
This statement is also true. The egg is fertilized inside of the flower.
Sporophytes produce spores for reproduction. In seed plants, the male reproductive structure produces MICROSPORES and the female reproductive structure produces MEGASPORES.
The statement is correct. The male gametophyte will fertilize the female gametophyte, known as the egg, to produce a zygote.
Gametophytes produce GAMETES through the process of MITOSIS.
False. The process of meiosis results in gametes, and not mitosis.
Hope that answers the question, have a great day!

The average distance between the center of the Earth and the center of its moon is 3.84 x 108 m. The mass of the earth is
5.97x1024kg. What is the orbital speed and period of Earth's moon?
V, - 1.02 x 10 m/s
V, = 3.26 x 10ʻm/s
T= 2.37 x 10° s = 27.4 days
T = 6.24 x 106 s = 82.2 days
b. V, = 2.03 x 10²m's;
d. V, - 1.02 x 10 m/s;
T = 3.67 x 10ºs = 39.4 days
T = 4.82 x 10Ⓡs = 57.3 days
Answer:
T = 2.37 x 106 s = 27.4 days would be the answer

match the following terms and definitions
a segment that contains the information for making proteins
A complex molecule containing the genetic code
Answer:
The terms are not included in the question but their terms are:
Gene- a segment that contains the information for making proteins
DNA- A complex molecule containing the genetic code
Explanation:
All living organisms contains genetic material (containing genes) in their cells. A gene is a segment of DNA that encodes the information needed for the synthesis of certain functional products called PROTEIN. The genes undergo expression i.e. transcription into RNA and translation into protein. This protein is responsible for the phenotype living organisms exhibit.
The genetic material in most organisms is the DNA, which is a complex molecule and one of the two types of nucleic acids containing long polynucleotide chains. The DNA stores the genetic information needed for the expression of genes i.e. genetic code. The information are stored in the four nucleotide bases (Adenine, Guanine, Cytosine and Thymine) that constitutes the DNA.
Why is the point of attachment of the frog's tongue considered to be advantageous?
Answer:
Frog's tongues are attached to the front of their mouths rather than at the back like humans.
Explanation:
This is an advantage because most frogs eat flies and insects and the like. Because they can flick their tongue a long way out they are able to catch food more effectively. This is an example of an adaptation.
A marine ecologist has constructed the conceptual model shown in the diagram. Which prediction can be made from using this model?
Hello. This question is incomplete. You forgot to put the diagram and answer options.
The diagram is in the figure attached below and the answer options are:
Where the tertiary consumers get their energy
How often primary producers are able to reproduce
When bacteria and fungi initiate the process of decomposition
Whether other secondary consumers are present
Answer:
Where the tertiary consumers get their energy
Explanation:
The diagram establishes the visualization of a food network where it is possible to visualize all the relationships between predators and game, in addition to being possible to observe the relationships between each trophy within a food chain.
With this, it is possible to determine all the ways that tertiary consumers are able to obtain energy and observe how that energy reached them.

A mother has one allele for dimples and one allele for no dimples. How many
of her gametes will carry the allele for dimples?
A. 0%
B. 25%
C. 100%
D. 50%
Answer:
50%, i believe
Explanation:
So the mother in the problem must have gotten her alleles from her mother and father. Who donated what we are not sure. All we know is that she got one allele for dimples and one allele for no dimples. These are part of the mother's somatic cell DNA. This DNA is duplicated during interphase, right before meiosis occurs as the mother begins to form her gametes, however.
