1- Animals survive when they compete. In limited resources, animals either compete, kill or co-operat. There are 3 ways animals complete with each other to get access o limited resources. These ways are:
- Parasitism – In this relationship, one animal gets benefit and the other gets hurt.
- Mutualism – in this interaction, both organisms benefits each other and survives.
- Commensalism- In this interaction, one organism gets benefit whereas the other gets nothing in return.
2- Living organisms are classified as:
- Producers
- Consumers
- Decomposers
Producers are the energy generators. They are the biggest source of energy for other levels. Consumers feed on producers and other animals. And the end, when consumers die, decomposers feed on them, break down their bodies and mix it with soil increase its fertility and the cycle of energy flow goes on.
Answer:
I believe the answer is A because if shrimp eat phytoplankton, and squid eat shrimp this should work. I am not positive but I hope this helps.
The gastrointestinal wall is composed of four layers or tunics:
- Mucosa
- Submucosa
- Muscularis mucosa
- Serosa
The innermost tunic of the wall is known as the mucosa or mucous membrane layer. The digestive tract's lumen is lined with it. The mucosa comprises epithelium, a layer of lamina propria, a loose layer of connective tissue, and the muscularis mucosa, a thin layer of smooth muscle.
The mucosa is surrounded by a substantial layer of loose connective tissue known as the submucosa. Blood arteries, lymphatic vessels, and neurons are also present in this stratum. The adventitia is a connective tissue that makes up the digestive tract's outermost layer above the diaphragm. It is referred to as serosa below the diaphragm.
