1. Answer;
A. energy flows in one direction and nutrients recycle.
Explanation;
-The movements of energy and nutrients through living systems are different because the energy flows in one direction and nutrients recycle.
-Energy is transferred between organisms in one direction in a food chain, but that interconnected food chains make a food web.
-Most ecosystems get their energy from the Sun. Producers can use sunlight to make usable energy by converting it into chemical energy or food. Consumers get some of that energy when they eat producers, they pass some of the energy to other consumers when they are fed on.
2. Answer;
Nitrogen fixation.
Nitrogen fixation depends on bacteria.
Explanation;
Nitrogen fixation is the process by which nitrogen is taken from its stable gas form (N2) in air and then converted into other nitrogen compounds (such as ammonia, nitrate and nitrogen dioxide) useful for other chemical processes.
-The nitrogen fixing bacteria are microorganism capable of converting atmospheric nitrogen into forms usable by plants. They include the free-living bacteria, which includes cyanobacteria, azotobacter etc. and others such as mutualistic bacteria such as Rhizobium.
Answer:
From superior to inferior;
1) Femoral
2)Sural
3) Popliteal
4)Tarsal
5) Calcaneal
Explanation:
1) Pertaining to the thigh is the femoral region. The femoral region derives its name from the femur which is a long bone present in the thigh region. The head of the femur articulates proximally with the hip bone at the hip joint or acetabulofemoral joint. The distal end of the femur articulates at the knee joint. The femoral region also has several other structures like the hamstring muscles and the femoral artery.
2) Pertaining to the calf is the sural body region. The calf the region behind the leg. It has several structures like the tibia and fibula bones and the gastrocnemius, soleus and plantaris muscles.
3) Pertaining to the heel is the calcaneal body region. The calcaneus is a big bone located in the posterior part of the foot. It is also called the heel bone. A major attachment to it is the Achilles tendon.
4) Pertaining to the back of the knee is the popliteal body region. The popliteal region is like a cavity made by surrounding muscles of the thigh and calf. It contains the popliteal artery and veins and several nerves running through it.
5) Pertaining to the ankle is the tarsal body region. The tarsal region contains tarsal bones which articulate with each other.
Answer:
All the answers are right because all of these occurs in meiosis
Even more islands because it will cool and form more islands
