Answer:
1. Plants utilize some of the incoming energy derived from photosynthesis for their own self-maintenance.
3. Plants and algae carry out both photosynthesis and cellular respiration.
5. Plants, algae, and cyanobacteria utilize light energy from the sun into their own biomass.
Explanation:
The gross primary productivity (GPP) of an ecosystem represents the rate at which the solar energy is captured during photosynthesis in a given period. Producers (plants, algae and cyanobacteria) perform cellular respiration to provide energy for their life processes. Cellular respiration consumes part of the total photosynthetic output. The energy available in tissues of producers after cellular respiration is called net primary productivity (NPP).
Therefore, NPP is the amount of biomass or the energy stored in the tissues of the producers for growth after cellular respiration for their normal daily activities and self-maintenance. So, NPP is always less than GPP.
The bonds that hold H2O2 together break apart and the atoms are rearranged to form water (H2O) and oxygen (O2) molecules. This happens slowly in store-‐bought hydrogen peroxide, so even in dark bottles, it will 'expire' in a year, or less if it's opened. ... And higher concentrations of H2O2 produce more oxygen.
The mesoderm is one of the embryonic layers together with the ectoderm and endoderm. The germ layer that gives rise to muscle is the <u>mesoderm</u>.
<h3>
What is the mesoderm?</h3>
Three embryonic layers are present in the blastoderm after segmentation. One of them is the <u>mesoderm</u>, which is located between the ectoderm and the endoderm.
Different tissues and cells are formed from the mesoderm, such as muscular, skeletal, circulatory, and connective tissues.
The correct anwer is mesoderm. The embyonic germ layer that gives rise to muscle is the mesoderm.

The killer whales primarily feed on the secondary consumers in the oceanic food web.
Explanation:
Killer whales are the tertiary consumers and occupy the highest position in the ocean food web. They are predating carnivores and feed on secondary consumers like other fishes, marine animals like leopard seals, sea turtles, dolphins, sea birds, etc. These secondary consumers in turn feed on primary consumers like zooplanktons, small fishes etc which feed on the primary producers like phytoplanktons. The energy flow is highest at the primary producer level and decreases as it goes up to the consumer levels.
Answer:
Sediments compact and cement together.
Explanation:
Generally, rocks are of three main types viz: Igneous, sedimentary and metarmophic rocks. Based on the question, the sedimentary rocks are that group of rocks formed by the coming together of sediments.
Sedimentary rocks can be formed in the following steps;
1. Rocks that have existed before undergoes weathering i.e. are broken down into smaller particles called sediments.
2. These sediments are then transported by currents e.g water
3. Deposited sediments accumulate and gathered round.
4. The accumulated sediments become compacted i.e. squashed and cemented i.e. stick together to form the sedimentary rock, in a process collectively lithification.
Hence, compaction and cementation (lithification) are the next steps in the process of sedimentary rocks formation after deposition.
