herbivores
There are many different food chains, so there are many second links, but in general the second link in a food chain is two words and it is a primary consumer.

Not exactly: you are confusing the terms used in food chains and food webs. A cow's diet is considered herbivorous, whereas the cow itself is a primary consumer because it eats only plants. In other words, the cow herself is deemed a primary consumer, and her diet is herbivorous.
The role of Algae in Ocean and food chains is to be producer for all different kind of consumer. in the food chain its show the feeding relation to consumer.
Yes. Linear food chains with one producer, one primary consumer, one secondary consumer and so on are an over-simplification, food webs would be more realistic of what goes on in ecosystems.
In food chains, the 'producers' are plants, who convert the energy from the sun into food through photosynthesis. A primary consumer is an animal who eats plants as food, and a secondary consumer is an animal who preys upon a primary consumer. A tertiary consumer will hunt other predators too. A weasel's main prey would be grass and seed-eating primary consumers, such as rodents and rabbits, but they do not prey on other carnivorous mammals. So that is why the weasel is a secondary consumer.
a frog is at the end of a french food chain
Food webs consist of different plants and animals, food chains are just animals in an environment with a producer, top consumer, and animals in the middle who are consumers.
because you basically just need a producer,1st consumer,2nd consumer,3rd consumer and decomposer
Well if you think about it this way (follow the OWL): a grasshopper eats grass and and a frog eats the grasshopper and the OWL eats the frog; in this situation the OWL is the tertiary consumer. In a different situation (follow the OWL): a mouse eats grass and an OWL eats the mouse; here, the OWL is the secondary consumer. You see, it all depends on the situation. Hope that helps :)
Yes, food chains do need a consumer. There are 4 types of consumers.
Fungi and bacteria would eat a dead fox or any other animal that is deceased.
