Decrease
Explanation : if there is less born and a greater number dead then math will tell you that the population would decrease have a nice day (:
not really familiar with all this but I think 1. Relative dating is where they estimate or relatively guess around how old it is so you could just put something like "an estimate of the age" or something
Answer:
atoms (2), community (11) , biome (13), biosphere (14), cells (5), organism (9), ecosystem (12), molecules (3), organ (7), organelles(4), organ system (8) , population (10), subatomic particles(1), and tissues (6)
Explanation:
Levels of organization in order from the simplest to the most complex are:
- Subatomic particles-neutrons, protons and electrons that make up the atom.
- atoms- Smallest particle of a substance that may or may not exist freely.
- molecules- two atoms combine to form molecule. e.g H₂
- organelles- organelles are functioning structures of a cell. e.g. Golgi apparatus.
- cells- organelles combine to form cell. e.g. Parenchyma cells.
- tissue- cells of similar origin and function form the tissue e.g. Cardiac tissue
- organ- tissues combine together to form organs. e.g. Heart
- organ system- many organs combine together to form system. e.g Circulatory system
- organism- several organ system combine to form an organism. e.g. Human being.
- population-organism of same species form a population.
- community- different population combine to form a community.
- ecosystem- communities live in a particular area and interact with the abiotic as well as biotic factors of that area to form ecosystem. e.g. pond ecosystem
- biome-A geographical area where several ecosystem sharing same abiotic factors thrive.e.g. tiaga biome
- biosphere- Narrow zone of the earth where the atmosphere , hydrosphere and lithosphere meet to support life.
c. Birth rates are high
Explanation:
A wide base in the population pyramid shows that there is a large population of young people with high fertility rate or birth rate and high death rate.
From the graph, it can also be concluded that narrow tip at the top shows that lesser older people are in the population.
This pyramid shown in the diagram is a triangular age pyramid. In this type of pyramid the pre-reproductive individuals are high reproductive individual are moderate and non-reproducing individual is less. In such pyramid we find population grows.
Suppose in a family of ten 6 are pre-reproductive, 2 moderate reproductive and 2 post-reproductive. We will see the in the course of moderate and post-reproductive will die and those six of pre-reproducing age will increase the population.
